Description: This antibody reacts with both alloantigens and all isoforms of the CD45 leukocyte common antigen (LCA), also known as Ly-5 or T200, found on all cells of hematopoietic origin, except erythrocytes. CD45 is a transmembrane glycoprotein which is expressed at high levels on the cell surface, and its presence distinguishes leukocytes from non-hematopoietic cells. The CD45 isoforms play complex roles in T-cell and B-cell antigen receptor signal transduction. This antibody is specific for mouse CD45 and suitable for immunohistochemical staining of Zinc-fixed and formalin fixed paraffin sections as well as acetone-fixed, frozen sections.
