MADCAM1 (Mucosal Vascular Addressin Cell Adhesion Molecule 1), BioAssay(TM) ELISA Kit (Mouse)

MADCAM1(Mucosal Vascular Addressin Cell Adhesion Molecule 1), also known as MACAM1, is a protein that is encoded by the MADCAM1 gene. By PCR-based analysis of somatic cell hybrids, Leung et al(1997) mapped the MACAM1 gene to chromosome 19. The protein encoded by this gene is an endothelil cell adhesion molecule that interacts preferentially with the leukocyte beta7 integrin LPAM-1(alpha4 / beta7), L-selectin, and VLA-4(alpha4/beta1) on myeloid cells to direct leukocytes into mucosal and inflamed tissues. It is a member of the immunoglobulin superfamily and is similar to ICAM-1 and VCAM-1. Sample Type: Cell culture supernates and serum. Intended Use: For quantitative detection of mouse MADCAM-1 in cell culture supernates and serum. Sensitivity: <10pg/ml, Range: 125-8000pg/ml, Specificity: Natural and recombinant mouse MADCAM-1, Test Principle: This mouse MADCAM-1 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for MADCAM-1 has been precoated onto 96-well plates. Standards(NSO, Q22-T365) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for MADCAM-1 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse MADCAM-1 amount of sample captured in plate.
