Background of OX40/TNFRSF4
Tumor necrosis factor receptor superfamily, member4, also known as ACT35 or CD134 is a cell surface glycoprotein that was discovered through the production of a monoclonal antibody raised against the HUT-102 cell line. It belongs to the tumor necrosis factor receptor superfamily. CD134 was mapped to 1p36 by fluorescence in situ hybridization. CD134 is the primary receptor for feline immunodeficiency virus. CD134 expression can promote viral binding and renders cells permissive for viral entry, productive infection, and syncytium formation. Stimulating the receptor can improve the response to a powerful virus vector and may be useful in vaccine development.

Question
Could you please give me more information on how EK1106 was tested on IHC-P and the specific antigen retrieval was used?
Verified Customer
Verified customer
Asked: 2019-09-03
Answer
The EK1106 was tested in staining of paraffin embedded formalin fixed tissues using sodium citrate buffer (10 mM, pH6) for about 15 minutes for antigen retrieval. It also been successfully tested to stain dog lymph node tissue of formalin fixed paraffin embedded tissue sections again using citrate buffer as the antigen retrieval agent.

Question
Q: can you suggest the dilution ratio of serum samples for detection of OX40 in Human cell lysates? I am trying to measure a few parameters and it requires 100ul of diluted samples for each well. We have limited sample volumes so we like to dilute as much as possible.
Verified Customer
Verified customer
Asked: 2019-07-07
Answer
A: unable to understand the physiological or pathological context of your samples we cannot recommend a dilution ratio without performing a pilot test with your samples. Here is how you can perform a pilot study on your own: perform a serial dilution of your samples on the OX40 ELISA kit to make sure you have a linear ascending curve followed by a plateau, which signifies the samples saturating the detection limit of the kit. Then you can pick the dilution ratios from samples in the linear part of the curve as your experimental dilution ratio.
If you are interested in using our ELISA service, you can also send us your sample and we will take care of everything for you. You can check our service details here: bosterbio.com/services/assay-services/ELISA-testing-service
Since you mentioned you have limited samples, our cost effective multiplex ELISA service would fit perfectly for your needs, where we can generate dozens of data points using as little as 25ul sample volume. Information on this service is also in the above link.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
T. Lopez
Verified customer
Asked: 2018-05-28
Answer
A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: if the enzyme conjugated OX40 antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the OX40 antigen?
E. Perez
Verified customer
Asked: 2018-04-22
Answer
A: The enzyme is always active. Avoid contaminating the substrate with enzyme prior to the incubation otherwise it compromises the assay with false positive signal.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis OX40 using the EK1106 Human OX40 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2018-02-24
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may alter the stabilityof samples. It is recommend to assay sample right after collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples in order to prevent protein degradation.

Question
Q: Can OX40 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
C. Turner
Verified customer
Asked: 2017-04-24
Answer
A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not valid for other sample types than we have tested: it means further investigation is needed. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been assessd by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please view the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Question
Q: is it okay to use citrate plasma as samples in Human OX40 Picokine® ELISA Kit (Catalog # EK1106)?
B. Dhar
Verified customer
Asked: 2014-06-28
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of OX40 causing degradation of its protein structure. OX40 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes required for detection and block the antigen antibody reaction. We have tested the OX40 ELISA, treating samples with a number of anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
S. Kumar
Verified customer
Asked: 2014-02-19
Answer
A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are included in the product insert. Components in lysate and lysis buffer can change immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.
