Background of B7-2/CD86
Cluster of Differentiation 86 (also known as CD86 and B7-2) is aprotein expressed on antigen-presenting cells that provides costimulatory signals necessary for T cell activation and survival. The CD86 gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. Using fluorescence in situ hybridization mapping, the CD86, like CD80, was mapped to human 3q21 and mouse chromosome 16, band B5. The antigen presentation coactivators B71 and B72, which are important in other immune-mediated thyroid diseases, are important for lymphocytic infiltration and the immune response against thyroid carcinoma.

7 Customer Q&As for Rat CD86/B7-2 ELISA Kit PicoKine®
Question
Q: how can I thaw whole blood sample for CD86 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-03-31
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 CD86 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring CD86 using the EK0712 Rat CD86 Picokine® ELISA Kit?
K. Gandhi
Verified customer
Asked: 2019-09-07
Answer
A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may affect 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 to prevent protein degradation.

Question
Q: if the enzyme conjugated CD86 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 CD86 antigen?
Verified Customer
Verified customer
Asked: 2019-09-01
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: What is the optimal O.D. value for CD86 ELISA kit? I used your CD86 ELISA on serum samples. For my positive control, I received an O.D. value of 0.826, while my negative control received a value of 0.136. I obtained both of these controls from the ELISA kit, where your kit's typical data shows O.D. values much higher than my positive control and your background is lower. My samples O.D. values are around 0.225 and the highest is only 0.357. is it safe to say these samples contain CD86 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2018-06-11
Answer
A: The absolute O.D. values may change according to incubation time. The more you incubate the higher the O.D. values are going to be. what you should focus on is whether your sample O.D. values are statistically significantly higher than your blank values. in the above example, you could extend your development time in the substrate incubation step to obtain higher O.D. values, as long as your negative controls' O.D. values are not increasing faster in relation to your positive controls. normally, a sample with O.D. value 2 standard deviations higher than your negative controls can be considered positive. We calculate the sensitivity of this ELISA kit by converting cutoff O.D. value, calculated as the average of 20 negative controls plus 2 standard deviations of the 20 negative controls, into a concentration. in other words, when we claim this CD86 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of CD86 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: how much samples can be assayed in a Picokine® ELISA Kit?
B. Banerjee
Verified customer
Asked: 2018-02-28
Answer
A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may depends upon the kit used so please refer to each datasheet for details.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
P. Yang
Verified customer
Asked: 2018-02-27
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.
