CD44 Std./H-CAM Ab-4 Mouse Monoclonal Antibody, Epredia™

Descripción

CD44 is a cell surface glycoprotein expressed on lymphocytes, monocytes, and granulocytes. CD44 is also known as homing cell adhesion molecule (H-CAM), Phagocytic glycoprotein-1 (PgP-1), ECM-III, HUTCH-1, or Hermes-1. CD44 has been implicated in cell migration, in lymphocyte homing, and in tumor metastasis. Ab-4 reacts with red cells pretreated with 2-aminoethylisothiouronium bromide (AET). Digestion of intact erythrocytes by trypsin treatment leaves a 50-54 kDa protein fragment attached to the membrane, while chymotrypsin leaves a somewhat similarly sized 51-56 kDa component that are recognized by Ab-4. This antibody enhances IL-2 production by CD2-transfected murine hybridoma stimulated by JY cells while it has no significant effect on IL-2 production by Jurkat cells stimulated with CD3, PMA, or CD2. Ab-4 enhances proliferation of PBL stimulated with CD2.
