B7-1/CD80 BioAssay(TM) ELISA Kit, Human

Sandwich ELISA quantitative detection kit for Human 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 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. B7-1 and B7-2 provide a costimulatory signal to T cells by interacting with CD28 and CTLA4. , Assay Range:, 62.5pg/ml-4000pg/ml, Sensitivity: < 10 pg/ml, Crossreactivity: There is no detectable cross-reactivity with other relevant proteins.
