Next Day 2 - 8°C

H-2Kb antibody, clone A4C8.1-Do9, recognizes the major histocompatibility complex (MHC) class I H-2K haplotype b (H-2Kb). MHC class I is ubiquitously expressed on the cell surface of nucleated cells and consists of a 45-kDa type I transmembrane glycoprotein (α-chain or heavy chain) and a 12-kDa soluble protein (β2-microglobulin, β2M)1, 2. The α-chain consists of three domains (α1, α2, and α3)3. α1 and α2 form the closed antigen-binding groove and bind to 8-10 aa peptides derived from cytosolic antigens4-6. β2M noncovalently associates with α3, which is essential for MHC stability. H-2Kb plays a critical role in the adaptive immune response by presenting endogenous antigens to cytotoxic CD8 T cells. MHC class I molecules can also present exogenous antigens to CD8 T cells via a process known as cross-presentation7. The T cell receptor (TCR)/CD3 complex of CD8 T cells interacts with peptide-MHC class I, which induces CD8 T cell activation and subsequent cell-killing. CD8 molecules also bind to MHC class I to augment TCR signaling8. In contrast to CD8 T cells, MHC class I is an inhibitory ligand for natural killer (NK) cells, promoting self tolerance9. MHC class I also contributes to the positive selection of CD8 T cells and NK cell specificity10, 11.

H-2Kb

CD3/TCR, CD8

Clone AF6-88.5, Anti-Mouse H-2Kb, recognizes an epitope on mouse MHC class I H-2K haplotype b. AF6-88.5 does not cross-react with other H-2K haplotypes, including d, f, j, k, p, q, r, s, u, v.

0.2 mg/ml

The AF6-88.5 antibody reacts with H-2Kb MHC class I alloantigen and is ubiquitously expressed on nucleated cells from mice of the H-2Kb haplotype, including C57BL/6. H-2Kb is involved in antigen presentation to T cells expressing CD3/TCR and CD8 proteins.

Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
