ERBB3 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level V-Erb B2 Erythroblastic Leukemia Viral Oncogene Homolog 3 (ErbB3) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level V-Erb B2 Erythroblastic Leukemia Viral Oncogene Homolog 3 (ErbB3) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Tyrosine-protein kinase that plays an essential role as cell surface receptor for neuregulins. Binds to neuregulin-1 (NRG1) and is activated by it; ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase (PubMed:20682778) . May also be activated by CSPG5 (PubMed:15358134) .

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 V-Erb B2 Erythroblastic Leukemia Viral Oncogene Homolog 3 (ErbB3) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to V-Erb B2 Erythroblastic Leukemia Viral Oncogene Homolog 3 (ErbB3) . 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 V-Erb B2 Erythroblastic Leukemia Viral Oncogene Homolog 3 (ErbB3), 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 V-Erb B2 Erythroblastic Leukemia Viral Oncogene Homolog 3 (ErbB3) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
