IGBP1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Immunoglobulin Binding Protein 1 (IGBP1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Immunoglobulin Binding Protein 1 (IGBP1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Alpha4; ALPHA-4; B cell signal transduction molecule alpha 4; bA351K23.1 (immunoglobulin binding protein 1 (CD79A) ) ; B-cell signal transduction molecule alpha 4; CD79a-binding protein 1; IBP1; immunoglobulin (CD79A) binding protein 1; immunoglobulin-binding protein 1; MRXS28; protein alpha-4; protein phosphatase 2/4/6 regulatory subunit; protein phosphatase 2A, regulatory subunit alpha-4; renal carcinoma antigen NY-REN-16.

Associated to surface IgM-receptor; may be involved in signal transduction. Involved in regulation of the catalytic activity of the phosphatases PP2A, PP4 and PP6 by protecting their partially folded catalytic subunits from degradative polyubiquitination until they associate with regulatory subunits.

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 Immunoglobulin Binding Protein 1 (IGBP1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Immunoglobulin Binding Protein 1 (IGBP1) . 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 Immunoglobulin Binding Protein 1 (IGBP1), 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 Immunoglobulin Binding Protein 1 (IGBP1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
