- Extra Details:
- 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. A number of different isoforms isoforms of CD45 are expressed on murine leucocytes depending on the pattern of altenative 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. Applications: Suitable for use in Flow Cytometry, Immunohistochemistry, Immunoprecipitation and Immunofluorescence. Other applications not tested. Recommended Dilutions: Immunohistochemistry: Frozen sections Optimal working dilutions to be determined by researcher. Hybridoma: Spleen cells from immunized DA rats were fused with cells of the rat Y3/Ag1.2.3 myeloma cell line Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
