| Specificity | This antibody recognises the murine CD45 cell surface antigen, a single pass type1 transmembrane glycoprotein also known as protein tyrosine phosphatase receptor type C (PTPRC) and originally termed Leucocyte Common Antigen (LCA). CD45 is a 180-220kDa glycoprotein expressed by all leucocytes.CD45 is encoded by 3 alleles in mice, differentially expressed by various inbred strains. The Ly5 gene was originally described with the gene product LY5.1 expressed in C57bl/6 and Ly5.2 expressed in SJL strains , this was subsequently expanded to include a third allele encoding Ly5.3. Further, in 1987 a reversal of nomenclature was instigated resulting in the allele in C57bl/6 becoming Ly5b encoding Ly5.2 and the allele in SJL mice becoming Ly5a encoding Ly5.1. Further changes were made in 1992 with Ly5.1 becoming CD45.1 (SJL) and Ly5.2 becoming CD45.2 (C57bl/6). Finally, following work demonstrating homology between the CD45 antigen and a receptor linked protein tyrosine phosphatase the CD45a gene was renamed Ptprca and CD45b renamed Ptprcb (Charbonneau et al. 1988; Zebedee et al. 1991).A number of different isoforms of CD45 are expressed on murine leucocytes depending on the pattern of alternative splicing of 3 exons termed A, B and C encoding regions of ~ 50 amino acids located at the N terminal region of the extracellular portion of CD45. The restricted proteins are termed CD45R with a designation depending on the expressed codon product. Rat anti mouse CD45 antibody, clone YW62.3 is reactive with all isoforms of murine CD45.N.B. Some reactivity with human tissue has been observed. |
