SIRPG ELISA Kit (Human)

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

BA77C3.1; CD172 antigen-like family member B; CD172g; CD172g antigen; signal-regulatory protein beta-2; signal-regulatory protein gamma; SIRP beta 2; SIRPB2; SIRP-B2; SIRPgamma; SIRP-gamma.

Probable immunoglobulin-like cell surface receptor. On binding with CD47, mediates cell-cell adhesion. Engagement on T-cells by CD47 on antigen-presenting cells results in enhanced antigen-specific T-cell proliferation and costimulates 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 Signal Regulatory Protein Gamma (SIRPg) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Signal Regulatory Protein Gamma (SIRPg) . 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 Signal Regulatory Protein Gamma (SIRPg), 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 Signal Regulatory Protein Gamma (SIRPg) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
