Additional reported applications (for the relevant formats) include: immunoprecipitation1, immunohistochemistry of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections.
CD45RB is an isoform of CD45 with exon 5 splicing (encodes B determinant). It is a 220 kD glycoprotein expressed on peripheral B cells, naïve T cells, thymocytes, weakly on macrophages, and dendritic cells. It plays a critical role in TCR and BCR signaling. As T cells become activated and progress from naïve to memory cells, CD45RB expression is downregulated. Additionally, functionally distinct CD4+ T cell subsets, which secrete differing cytokine profiles, can be separated by CD45RB intensity. The primary ligands for CD45 are galectin-1, CD2, CD3, CD4 and Thy-1.
Structure:
Phosphatase receptor (CD45 gene exon 5), 220 kD
Distribution:
Peripheral B cells, naïve T cells, most thymocytes, low density on macrophages and dendritic cells
Function:
Phosphatase, T cell development and activation
Ligand Receptor:
Galectin-1, CD2, CD3, CD4, Thy1
