Anti-CD45 Monoclonal Antibody

Background Information

CD45, also known as leukocyte common antigen (LCA), protein tyrosine phosphatase, receptor type I (PTPR) is a type I transmembrane protein encoded by PTPR gene specifically expresses in hematopoietic cells. PRPR gene has 34 exons. Dfferentially spliced transcription of exon 4, 5 and 6 yields 6 isoforms: ABC (exon 4, 5 and 6), AB (exon 4 and 5) or BC (Exon 5 and 6), A (only exon 4), B (only exon 5) and O (no exon 4, 5, or 6). Conventional monoclonal antibodies(mAbs) raised against CD45 have reactivity against all isoforms, while restricted mAB only reacts to specific isotypes (CD45RA, CD45RB, CD45RO). BMI-CD45Ab13, identifies all three major subsets of  leukocyte (Granulocyte, monocyte and lymphocyte) and was selected by Professor Leon Terstappen to participate in CANCER-ID Consortium.


This antibody is useful in Flow Cytometry, Enzyme-Linked Immuno Sorbent Assay, Western Blot, Immunocytochemistry, Immnofluorescence.
