Anti-CD49d (Integrin alpha-4, CD49 Antigen-like Family Member D, Integrin alpha-IV, VLA-4 Subunit al

CD49d is a 150 kD alpha integrin chain known as alpha4 integrin or VLA-4 alpha chain. It forms a heterodimer with either integrin beta1 (alpha4beta1, VLA-4) or beta7 (alpha4beta7). CD49d is expressed broadly on T lymphocytes, B lymphocytes, monocytes, thymocytes, eosinophils, basophils, mast cells, NK cells, dendritic cells, and some non-hematopoietic cells, but not on normal red blood cells, platelets or neutrophils. VLA-4 binds to VCAM-1 (CD106) and fibronectin. alpha4beta7 is the receptor for VCAM-1 and MAdCAM-1. CD49d participates in mononuclear cell trafficking to endothelial sites of inflammation and has roles in cell-cell interactions and cell adhesion to extracellular matrices. CD49d is involved in lymphocyte migration, T cell activation, and hematopoietic stem cell differentiation. CD49d is a marker to isolate pure populations of Treg cells due to its absence on Foxp3+ cells. Applications: Suitable for use in Flow Cytometry and Immunohistochemistry.
