CD44 Antibody [F10-44-2] (PE)

CD44, also known as phagocytic glycoprotein-1 (Pgp-1), exists as a large number of different isoforms resulting from alternative RNA splicing. The major isoform expressed on lymphocytes, myeloid cells, and erythrocytes is a glycosylated type I transmembrane protein. Other variable isoforms containing glycosaminoglycans have molecular weights ranging from 110 to 250 kDa and are widely expressed on hematopoietic and non-hematopoietic cells. CD44 contributes to the adhesion of leukocytes to endothelial cells, stromal cells, and the extracellular matrix. It also plays a functional role in cell migration, lymphocyte homing, and adhesion during hematopoiesis and lymphocyte activation.
