Question
I purchased your EK0858 Mouse TNFSF4/OX40L ELISA Kit for IHC/IHC-Fr. Could you possibly share with me some images? Cheers!
Verified Customer
Asked: 2020-03-03
Answer
The product EK0858 Mouse TNFSF4/OX40L ELISA Kit was being tested using frozen human inflammatory lymph nodes by immunofluorescence resulting positive subgroup cells. We do not have an image of this EK0858 antibody in IHC-Fr.

Question
Q: if the enzyme conjugated OX40 Ligand 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 Ligand antigen?
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: we need your suggestion regarding the dilution ratio of serum samples for detection of OX40 Ligand in Mouse serum? I am trying to measure a few parameters and it requires 100ul of diluted samples for each well. We have limited sample quantitys so we like to dilute as much as possible.
L. Varma
Asked: 2019-09-12
Answer
A: without having an understanding 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 Ligand 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: is it okay to use citrate plasma as samples in Mouse OX40 Ligand Picokine® ELISA Kit (Catalog # EK0858)?
W. Williams
Asked: 2019-07-17
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of OX40 Ligand causing degradation of its protein structure. OX40 Ligand 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 Ligand ELISA, treating samples with different 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: which procedure should I follow in order to thaw whole blood sample for OX40 Ligand ELISA after freezing?
S. Roberts
Asked: 2019-06-10
Answer
A: do not freeze and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test OX40 Ligand for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: Can OX40 Ligand ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Asked: 2018-11-12
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 suitable for other sample types than we have tested: it means further investigation is a must. 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 check 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.
