General description

Anti-CD45 antibody detects endogenous levels of total CD45 protein.
The CD45 (cluster of differentiation 45) gene is mapped to human chromosome 1q31.3-q32.1. It codes for a type I transmembrane protein and is expressed in nucleated hematopoietic cells along within its precursors. The protein consists of a varying extracellular domain and a highly conserved intracellular domain.

Immunogen

The antiserum was produced against synthesized peptide derived from human CD45.

Immunogen Range: 981-1030

Application

Anti-CD45 antibody produced in rabbit has been used in:
  • immunohistochemistry staining
  • immunofluorescence staining
  • immunostaining

Biochem/physiol Actions

The Cluster of differentiation 45 (CD45) facilitates the regulation of lymphocyte signaling and SRC family kinase Lck. This protein participates in the polymorphism in several mammalian species.
The protein encoded by CD45 (cluster of differentiation 45) is a prototypic receptor and exhibits phosphatase activity. CD45 is found to control T-cell mediated BCR-signaling.
