Description
Product Characteristics: This antibody reacts with CD45RC on pre-B lymphocytes,B cells,CD8+ T suppressor/cytotoxic cells,and a subset of CD4+ T helper (Th)lymphocytes. It weakly reacts with thymocytes.4 CD45RC is a high-molecular-weight isoform of CD45 (Leukocyte Common Antigen),its level of expression distinguishes subpopulations of CD4 +T cells with Th1-like and Th2-like effector functions. Levels of expression of CD45RC have also been reported to distinguish resting from activated T cells at various stages of maturation. CD45 is a member of the Protein Tyrosine Phosphatase (PTP)family:Its intracellular (COOH-terminal)region contains two PTP catalytic domains,and the extracellular region is highly variable due to alternative splicing of exons 4,5,and 6 (designated A,B,and C,respectively),plus differing levels of glycosylation. The CD45 isoforms detected in the rat are cell type-,maturation-,and activation state-specific. The CD45 isoforms play complex roles in T-cell and B-cell antigen receptor signal transduction.
Target Information: member of a family of heavily glycosylated leukocyte cell surface glycoproteins\, displays extensive O-glycosylation [RGD, Feb 2006]
