Product Name	CD45 Antibody
Antibody Type	Primary Antibodies
Product description	CD45 is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus belongs to receptor type PTP. The CD45 gene is specifically expressed in hematopoietic cells. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling. This PTP also suppresses JAK kinases, and thus functions as a regulator of cytokine receptor signaling.1) Stanton, T., et al., Proc. Natl. Acad. Sci. U.S.A. 100(10):5997-6002 (2003).

Application

Flow cytometric analysis of jurkat cells using CD45 Antibody (bottom histogram) compared to a negative control cell (top histogram). FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.
Application

Formalin-fixed and paraffin-embedded human tonsil reacted with CD45 Antibody , which was peroxidase-conjugated to the secondary antibody, followed by DAB staining.
Application

Antibody is used in Western blot to detect CD45 in jurkat cell lysate.
