CD80 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level B-Lymphocyte Activation Antigen B7-1 (LAB7-1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level B-Lymphocyte Activation Antigen B7-1 (LAB7-1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Activation B7-1 antigen; B7; B7.1; B7-1; BB1; B-lymphocyte activation antigen B7; CD28LG; CD28LG1; CD80 antigen (CD28 antigen ligand 1, B7-1 antigen) ; costimulatory factor CD80; costimulatory molecule variant IgV-CD80; CTLA-4 counter-receptor B7.1; LAB7; T-lymphocyte activation antigen CD80.

Involved in the costimulatory signal essential for T-lymphocyte activation. T-cell proliferation and cytokine production is induced by the binding of CD28, binding to CTLA-4 has opposite effects and inhibits T-cell activation.

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to B-Lymphocyte Activation Antigen B7-1 (LAB7-1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to B-Lymphocyte Activation Antigen B7-1 (LAB7-1) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain B-Lymphocyte Activation Antigen B7-1 (LAB7-1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of B-Lymphocyte Activation Antigen B7-1 (LAB7-1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
