Background
Basigin is a member of the immunoglobulin superfamily that is also known as EMMPRIN, short for extracellular matrix metalloproteinase inducer, and recently has been designated CD147 (cluster of differentiation 147).[1][2] It is a member of the immunoglobulin superfamily, with a structure related to the putative primordial form of the family. As members of the immunoglobulin superfamily play fundamental roles in intercellular recognition involved in various immunologic phenomena, differentiation, and development, basigin is thought also to play a role in intercellular recognition (Miyauchi et al., 1991; Kanekura et al., 1991).This protein is a determinant for the Ok blood group system. Basigin is a type I integral membrane receptor that has many ligands, including the cyclophilin (CyP) proteins Cyp-A and CyP-B and certain integrins.[3][4][5] It is expressed by many cell types, including epithelial cells, endothelial cells and leukocytes. The standard product used in this kit is recombinant human Emmprin, A22-H205, 7.4KDa.
Principle
The ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. The target specific antibodies are precoated onto 96-well plates. The target from the sample is bound to the microwell. The biotinylated target specific detection antibodies are added to the microwells and followed by washing with the PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with the PBS or TBS buffer. TMB, the HRP (horseradish peroxidase) substrate, is used to visualize color change resulting from the HRP enzymatic reaction. TMB is catalyzed by HRP to produce the blue color. The color changes into yellow after the acidic stop solution is added. The density of the yellow color is proportional to the target amount from the sample captured in the microwells.
