The mouse monoclonal antibody clone 2D1 binds to human CD45. Human CD45, also known as Leukocyte Common Antigen (LCA), is one of the most abundant hematopoietic markers. It is a 180-220 kDa single-chain type I transmembrane protein expressed at high levels on all cells of hematopoietic origin, except erythrocytes, platelets, and non-hematopoietic cells. Specifically, CD45 is found on the surface of T and B lymphocytes, natural killer cells, monocytes, macrophages, dendritic cells, neutrophils, eosinophils, and basophils. CD45 functions as a protein tyrosine phosphatase with several isoforms, each generated and expressed in cell-specific patterns. With its broad cell distribution, CD45 plays a critical role in many leukocyte functions by regulating signal transduction and cell activation associated with the T cell receptor, B cell receptor, and IL-2 receptor. Other forms of CD45 with more restricted cellular expression include CD45R (B220), CD45RA, CD45RB, and CD45RO. It is reported that clones 2D1 and HI30 anti-human CD45 clones can reciprocally block the binding of each other to CD45.

RECOMMENDED USAGE

Flow cytometry: The suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL.
