General description

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target description

MHC class I polypeptide-related sequence A (UniProt: Q29983; also known as MIC-A) is encoded by the MICA (also known as PERB11.1) gene (Gene ID: 100507436) in human. MIC-A is a single-pass type I membrane protein that act as stress-induced self-antigen that are recognized by gamma-delta T cells and serves as ligands for the KLRK1/NKG2D receptor. It is recognized by cytotoxic gamma-delta T cells expressing the TCR variable region V delta1. It is expressed on the cell surface in gastric epithelium, endothelial cells, and fibroblasts and in the cytoplasm in keratinocytes and monocytes. Its expression has also been reported in tumor cells. It is proteolytically cleaved and released from the cell surface of tumor cells which impairs KLRK1/NKG2D expression and T-cell activation. MIC-A can be induced by heat shock and by exposure to DNA damaging conditions. It is synthesized with a signal peptide (aa 1-23), which is cleaved off in the mature form. Their mature forms contain an extracellular domain (aa 24-307), a transmembrane domain (aa 308-328), and a cytoplasmic domain (aa 329-383). Two isoforms of MIC-A have been described that are produced by alternative splicing. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
