| Storage | Supplied in 10 mm sodium HEPES (pH 7.5), 150 mm NaCl, 100 µg/mL BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.For a carrier free (BSA and azide free) version of this product see product #98819. |
| Specificity/Sensitivity | CD45 (D3F8Q) Rabbit mAb recognizes endogenous levels of total CD45 protein. Non-specific staining was observed in mouse kidney by immunohistochemistry. This antibody is predicted to react with both the CD45.1 and CD45.2 alleles. |
| Species Reactivity | Mouse |
| Source/Purification | Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala1258 of mouse CD45 protein. |
| Background | The protein phosphatase (PTP) receptor CD45 is a type I transmembrane protein comprised of a pair of intracellular tyrosine phosphatase domains and a variable extracellular domain generated by alternative splicing (1). The catalytic activity of CD45 is a function of the first phosphatase domain (D1) while the second phosphatase domain (D2) may interact with and stabilize the first domain, or recruit/bind substrates (2,3). CD45 interacts directly with antigen receptor complex proteins or activates Src family kinases involved in the regulation of T- and B-cell antigen receptor signaling (1). Specifically, CD45 dephosphorylates Src-family kinases Lck and Fyn at their conserved negative regulatory carboxy-terminal tyrosine residues and upregulates kinase activity. Conversely, studies indicate that CD45 can also inhibit Lck and Fyn by dephosphorylating their positive regulatory autophosphorylation site. CD45 appears to be both a positive and a negative regulator that conducts signals depending on specific stimuli and cell type (1). Human leukocytes including lymphocytes, eosinophils, monocytes, basophils, and neutrophils express CD45, while erythrocytes and platelets are negative for CD45 expression (4). |
