Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to specific amino acids in the N-terminal region of HLA-B protein.

Background

The human leukocyte antigen (HLA) system is a gene complex encoding the major histocompatibility complex (MHC) proteins in humans. These cell surface proteins are responsible for the regulation of antigen-specific immunity in humans. HLA genes are highly polymorphic, allowing them to fine-tune the adaptive immune response. HLAs corresponding to MHC class I (HLA-A, B, and C) present small peptide antigens from inside the cell, approximately 8 to 10 amino acids in length, to CD8+ T lymphocytes to activate a cytotoxic T cell response (1,2). HLA-B (major histocompatibility complex, class I, B) is a heterodimer consisting of a heavy chain and light chain (beta-2 microglobulin) and is the most polymorphic of the HLA-I genes (3). HLA-B is expressed in nearly all cells, and variations of the HLA gene have been associated with hundreds of diseases and conditions (4).
