IL12B ELISA Kit (Guinea pig)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Interleukin 12B (IL12B) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Interleukin 12B (IL12B) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

CLMF p40; cytotoxic lymphocyte maturation factor 40 kDa subunit; IL-12 p40; IL-12 subunit p40; IL-12B; interleukin-12 p40 subunit; interleukin-12 subunit beta.

Cytokine that can act as a growth factor for activated T and NK cells, enhance the lytic activity of NK/lymphokine-activated killer cells, and stimulate the production of IFN-gamma by resting PBMC.

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 Interleukin 12B (IL12B) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Interleukin 12B (IL12B) . 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 Interleukin 12B (IL12B), 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 Interleukin 12B (IL12B) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
