Background for Brain-derived neurotrophic factor
Brain-derived neurotrophic factor(BDNF) is a prosurvival factor induced by cortical neurons that is necessary for survival of striatal neurons in the brain. It is a secreted protein with the molecular weight of 27.8kDa, consisting of 247 amino acids. It is known to promote neuronal survival and differentiation. BDNF shares substantial amino acid sequence identity with nerve growth factor(NGF). BDNF and neurotrophin-3(NT-3) are two recently cloned neurotrophic factors that are homologous to NGF. mRNA products of the BDNF and NT-3 genes are detected in the adult human brain, suggesting that these proteins are involved in the maintenance of the adult nervous system. BDNF and other neurotrophins are critically involved in long-term potentiation(LTP). BDNF-mediated LTP is induced postsynaptically. BDNF has trophic effects on serotonergic(5-HT) neurons in the central nervous system. BDNF has an essential maintenance function in the regulation of anxiety-related behavior and in food intake through central mediators in both the basal and fasted state. It plays a role in treating breathing disorders such as respiratory insufficiency after spinal injury. The mature form of BDNF is identical in all mammals examined, and the gene encoding human BDNF to chromosome 11, band p13.

Customer Q&As
A: None of the components in our ELISA kits are produced in humans or primates.
Q: What is the volume of the recombinant protein control? What is its shelf life?
Keywords: expiration, storage, temperature, size
Keywords: expiration, storage, temperature, size
A: The volume of the control is around 100pg. If unopened, the shelf life of the control is the same as the whole kit - "Store at 4˚C for 6 months, at -20˚C for 12 months." The reconstituted control can be stored at -20˚C for 2 days.
Q: Will it be okay to run the experiment if I accidentally used the wrong buffer (e.g. sample diluent buffer) for antibody dilution instead of the antibody diluent buffer? Keywords: dilution, replace, substitute, sample buffer
A: Using the sample diluent buffer for antibody dilution instead of the antibody diluent buffer will negatively affect the test result to some extent. The values of both standard and sample might be lower than the normal values.
Q: Will using RIPA lysis system for lysate preparation have an effect on the ELISA Keywords: lysis buffer, TBS, PBS, washing buffer, lysate preparation, RIPA, ELISA
A: Using RIPA lysis system will not have any effect on the ELISA.
Q: When choosing between lysis buffer and PBS to prepare tissue lysates, is there any benefit to using one over the other?
Keywords: lysis buffer, TBS, PBS, washing buffer, lysate preparation, RIPA, ELISA
A: RIPA lysis buffer is the preferred buffer for lysate preparation because it lyses tissues more thoroughly than PBS.
Q: Is baculovirus used in the product of EK0309?
Keyword: manufacturing
A: Yes, baculovirus is used during the production of EK0309 as a transfection factor.
Q: Is the sf21 expression system referring to insect cells?
Keywords: insect cell line, immunogen, IPLB-Sf21-AE
A: Yes, sf21 is an insect cell expression system.
Q: Does EK0309 measure all BDNF isoforms (pro and mature BDNF)?
Keywords: isoform detection, pro BDNF, mature BDNF
A: EK0309 can measure both pro and mature BDNF. However, EK0309 cannot differentiate between pro BDNF and mature BDNF.
Q: The protocol says to use neutral PBS and provides a recipe. Could I use neutral PBS made with KCl or KH2PO4 (common constituents for most PBS recipes) instead?
Keywords: protocol, alternative buffer, applications, reagent recipe
A: Yes, it is ok to use common PBS recipes. We have tried many types of buffers with common constituents, and no significant difference was observed whatsoever.
Q: Why are my O.D. values different than your values on the datasheet?
Keyword: troubleshooting, reference
A: We detected the kit in our lab and got our values on the datasheet before delivery, but protein activity will decrease as time goes on, so you may get lower O.D. values than ours. However, it should still be in a reasonable range and the standards can be used to calculate sample values. Good linearity of curve is more important than the actual numerical value.
Q: On the ELISA kit datasheet it says "HRP substrate TMB was used to visualize HRP enzymatic reaction." What is HRP and which part of the kit contains HRP?
Keyword: kit components, reagents, protocol
A: It means Avidin-Biotin-Peroxidase Complex(AR1103) and you could find it in Kit Components.
Q: Do you offer any ELISA kits that can work with whole blood samples instead of plasma or urine?
Keyword: applications
A: We test serum and plasma routinely, and there is very little difference between serum, plasma and whole blood. The whole blood also contains proteins we need to test. The kit can be used to test whole blood in theory.
Q: Could cell lysate also be tested by this kit? What is your advice on how to prepare cell lysates?
Keyword: application, sample, protocol
A: We didn't test cell lysate, the kit can work if the concentration of BDNF in cell lysate is in the test range of the kit. The customer can have a try if he wants to detect it. The general preparation of cell lysate is as follows:
Collect cells and rinse cells with PBS. Homogenize and lyse cells thoroughly in lysate solution(Cell Protein Extraction Reagent, Catalog# AR0103). Centrifuge cell lysates at approximately 10000 X g for 5 min to remove debris. Aliquots of the cell lysates were removed and assayed.
Q: Does silicic acid (formula SiOH4) affect the results of the ELISA assay?
Keyword: protocol, reagents
A: The acid may affect the binding of antigen to antibody, it is not recommended to use. That being said, it is unlikely to affect the reaction if the solution remains an overall neutral environment.
Q: Is there lot-to-lot variation of the ELISA kits? What are Boster's general services when I have questions about your kits?
Keyword: technical support, help, customer service
A: The NIBSC/WHO 1st International Standard is evaluated, we always test our kits before delivery, and customers can find the test result on the protocol. If the customer needs technical support from us to analyze their data, please contact us and we ask that you provide us the following information: the lot# and production date, and when did the customer detect the kit.
Q: The results of my standards do not look correct, what could be the problem?
Keyword: troubleshoot, protocol
A: Double check the protocol for plate washing. It should be examined on three aspects: 1) Did you make the washing buffer correctly? 2) How long did you let the buffer stay in wells? 3) What was the volume of the washing buffer added to each well? In addition, pay attention when adding sample to avoid contamination. And we suggest testing the standards again. Values of standards at low concentration are more affected than that at higher concentration, so customer can still get expected values at high concentration even if there is an error. If problems persist, please contact technical support with the catalog and lot number of your product.
Q: What is the well depth of the 96 well plates for the ELISA kits?
Keyword: well capacity, product size
A: The well depth is 300ul, and the max capacity is 350ul. The height of the well is 1.1 cm, and the internal size is 1 cm.
Q: Does this kit contain any recombinant protein produced by viral systems?
Keyword: expression
A: The kit does not contain protein produced by viral system, the express system of it is sf21.
Q: The kit does not include wash solution, what should I do?
Keyword: wash buffer
A: Our Elisa kits do not come with wash solution, but we have included information about how to make washing buffer on the datasheet. Please refer to the "Material Required But Not Provided" section. We also offer washing buffer for sale separately (Phosphate Buffered Saline Powder SKU: AR0030).
Q: For your ELISA kits, are the capture and detection antibodies polyclonals or monoclonals?
Keyword: antibody clonality
A: This information can be found for each kit under the "Properties" section, and you can find the immunogen sequence information in the "Overview" section.
Q: Do your ELISA kits come with sealants or plate covers?
Keyword: storage, sequential use
A: The kit can be used within a month sequentially if it's opened and stored at 4 degree. There is no need to use sealants, the plate can be packaged with aluminum foil bag, and for other reagents keep bottle tightly closed.
Q: What is the concentration of Sodium Azide in your Elisa kits?
Keyword: preservative
A: Our Elisa kits contain 0.02% Sodium Azide. All of the components except TMB colour developing reagent and stop solution contains 0.02% Sodium azide as the preservative.
Q: Are there positive and negative controls available for my ELISA kit?
Keyword: positive control, negative control
A: We can provide a recombinant protein as a control. It costs $50 per control and takes 2 weeks to manufacture. We cannot provide a positive or negative control in serum.
Q: Why do I get positive results for my knockout (KO) model when used as a control?
A: The knockout (KO) model may contain truncated forms of the target protein which can be detected by the ELISA assay.
Q: How long do I soak my plate in the wash buffer?
A: The plate should soak in 0.3mL PBS or TBS wash buffer for at least 1-2 minutes in an automated wash station.
Q: Can I use Tween in my wash buffer?
A: While it is not recommended to use Tween in your wash buffer, small amounts (<0.1% concentration) may decrease background due to insufficient blocking.
Q: What plate type do I use to set up the microplate reader?
A: Our plates are made with the Corning costar plates similar to the DNA-BIND 96 -well plates.
Q: I am interested in performing Western Blot (WB) using the antibodies from your human and mouse BDNF ELISA kits. Is it possible to order the primary antibody (the capture antibody) that is pre-coated in the wells for the sandwich ELISA? (In this case that would be the monoclonal antibody from rat for the mouse kit, and the monoclonal antibody from mouse for the human kit). Is it also possible to order your secondary antibody which is the biotinylated detection polyclonal antibody from goat specific for BDNF?
A: The antibodies used in those ELISA kits are not fully validated on WB. Also, since these antibodies are made from recombinant proteins, they are often less reactive to retrieved antigens in WB or IHC due to the lack of tertiary structure in the retrieved antigens. If you want to test human and mouse BDNF with WB, please use our anti-BDNF antibody (PB9075). Further, you can separately buy our secondary antibodies.
Q: I got very low OD values for the BDNF standard that you provided. What should I do?
A: Try to repeat your experiment by extending your incubation times as follows: samples (150 min), biotinylated antibodies (70-80 min), ABC reagent (45 min) and TMB (30 min).
Q: What should I use for negative control?
A: Please contact us for negative control suggestions. You can also check expression databases such as genecards, uniprot etc. Due to logistic reasons, we do not sell serum or lysates that we use internally for positive or negative control.
Q: Where can I find troubleshooting information? What should I do if I have unexpected bands, high background, no signal, weak signal
A: You can find Boster's troubleshoot guides under tech support tab. Please contact us for further assistance on troubleshooting your experiment.
Q: What is the normal level of this protein in my sample of interest?
A: We have reviewed literature and have gathered this information for most of our ELISA kits. You can find this information on the product page or contact us if you cannot find it. However this information is only suggestive and cannot replace pilot studies in determining the optimal sample dilution ratio.
Q: Is the plate separable? Can I use only part of the kit and save the rest for later? How many samples can I run with one kit?
A: Yes the plate is separable. There are 12 strips of 8 wells each, all removable from the plate. The amount of samples you can run depend on a few factors. In the most common ELISA set up, you will use two strips for standards, and 10 strips for samples using duplicates, which let you run up to 40 samples per kit. Contact us if you have questions regarding other situations.
Q: Does the kit contain sample preparation reagents? How do I prepare my samples?
A: Since different sample types require different reagents, we do not include them in the ELISA kit. However we do have each reagent mentioned in the file below available at very reasonable prices. Be sure to check them out. For sample preparation protocols please download the file below: https://www.bosterbio.com/media/pdf/Boster_Sample_Preparation_Protocols.pdf
Q: Can this ELISA kit work on brain tissue homogenate, cell culture supernatant, saliva, urine, serum, whole blood or any other sample type?
A: In theory the ELISA kit will work for all sample types if the target protein is present at a level that falls within the linear range of the ELISA kit detection range. We guarantee the kit to work on the sample types that we have tested. If you want dilution ratio suggestions on these sample types please contact our technical support. For sample types that we have not tested for, we suggest you run pilot experiments to decide the optimal sample dilution.
Q: Can this ELISA kit react with the pro-form of the target protein? Can this ELISA kit react with an isoform of the protein?
A: In general, unless otherwise specified, the ELISA kit is pan-specific, meaning that it will react with all different forms of the target protein if they share the majority of the target protein's sequence. The capture and detection antibodies are reactive to the entire sequence of the standard protein. You can find the sequence information of the standard protein in the "immunogen" section. For more information about the specificity of the kit for your particular experiment, please contact our techincal support.
Q: Can this ELISA kit react with human, mouse, rat or other species?
A: If the kit is reactive to another commonly used species (human, mouse, and/or rat), we would have listed it as a separate product. If you want to check cross-reactivity to a species that is not included in the 3 species listed above, please contact our technical support for more information. As a rule of thumb, if the sequences are 90%+ identical, there is a high chance of cross-reactivity for your species of interest.
