human ... PTPRC(5788)

Descrizione generale

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.

Immunogeno

Human thymocytes and T lymphocytes

Applicazioni

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.

Azioni biochim/fisiol

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.

CD45 is one of the most abundant leukocyte cell surface glycoproteins and is expressed exclusively upon cells of the hematopoietic system. Different isoforms of CD45 are generated by alternative splicing and are expressed in cell type-specific patterns on functional subpopulations
