MICA BioAssay(TM) ELISA Kit, Human

Sandwich ELISA quantitative detection kit for Human MICA in cell culture supernates, cell lysates, tissue homogenates and serum. MHC class I polypeptide-related sequence A is a protein that in humans is encoded by the MICA gene. The MICA gene encodes a 383-amino acid polypeptide with a predicted mass of 43kD.The MICA and MICB genes occur in a 200-kb region spanning the TNFA and TNFB cluster at 6p21.3.2 MICA and the closely related MICB were recognized by intestinal epithelial T cells expressing diverse V-delta-1 gamma/delta TCRs. The MICA protein product is expressed on the cell surface, although unlike canonical class I molecules does not seem to associate with beta-2-microglobulin. It is further distinguished by its unusual exon-intron organization and preferential expression in fibroblasts and epithelial cells. It is thought that MICA functions as a stress-induced antigen that is broadly recognized by NK cells, NKT cells, and most of the subtypes of T cells. MICA and other members of this family may have been selected for specialized functions that are either ancient or derived from those of typical MHC class I genes, in analogy to some of the nonclassic mouse H-2 genes. The standard product used in this kit is recombinant MICA, which is composed of 286 amino acids with the molecular mass of 59kD. , Assay Range:, 62.5pg/ml-4000pg/ml, Sensitivity: < 10 pg/ml, Crossreactivity: There is no detectable cross-reactivity with other relevant proteins.
