Mouse B7-1/CD80 ELISA Kit - 1 Kit (96 Wells)Our Mouse B7-1/CD80 ELISA Kit is a sandwich ELISA intended for the quantitative determination of mouse B7-1/CD80 in cell culture supernates and serum.
The protein CD80(Cluster of Differentiation 80) is a molecule found on activated B cells and monocytes which provides a costimulatory signal necessary for T cell activation and survival. It is also known as B7.1. The cDNA for B7-1 predicts a type I membrane protein, i.e., one synthesized with a signal peptide that is cleaved upon translocation across the endoplasmic membrane. The protein is predicted to contain 2 extracellular domains structurally similar to those of Ig, a hydrophobic transmembrane region, and a short cytoplasmic domain. The CD80 and CD86(601020) genes encode B7-1 and B7-2, respectively, which are structurally similar members of the immunoglobulin superfamily expressed on a variety of hematopoietic cell types. stated that B7-1 and B7-2 provide a costimulatory signal to T cells by interacting with CD28 and CTLA4. The standard product used in this kit is recombinant B7-1, D37K245, which is composed of two single chains acids with the dipolymer.
