General description
The antibody MEM-28 reacts with all alternative forms of human CD45 antigen (Leukocyte Common Antigen), a 180-220 kDa single chain type I transmembrane protein expressed at high level on all cells of hematopoietic origin, except erythrocytes and platelets.
The cluster of differentiation 45 (CD45) 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
Human thymocytes and T lymphocytes
Application
The reagent is designed for Flow Cytometry analysis of human blood cells using 20 μL reagent / 100 μL of whole blood or 1e6 cells in a suspension. The content of a vial (2 mL) is sufficient for 100 tests.
Biochem/physiol Actions
Cluster of differentiation 45 (CD45) functions as a prototypic receptor and exhibits phosphatase activity. CD45 is implicated in the regulation of T-cell mediated B cell antigen receptor (BCR)-signaling. The encoded protein plays an essential role in antigen-stimulated proliferation of T lymphocytes and in thymic development. CD45 negatively regulates cytokine receptor signaling via suppressing JAK (Janus kinase) activity.
