CD44 (HCAM, Homing Cell Adhesion Molecule, Pgp-1, Phagocytic Glycoprotein-1, Hermes Antigen, Lymphocyte Homing Receptor, ECM-III, HUTCH-1)(BSA & Azide Free)

May be stored at 4 degree C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degree C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Recognizes CD44 at 80-95kD. Epitope is resistant to digestion by trypsin and chymotrypsin. Reacts with red cells pretreated with 2-aminoethylisothiouronium bromide (AET). Digestion of intact erythrocytes by trypsin treatment left a 50-54kD protein fragment attached to the membrane. Digestinon with chymotrypsin left a somewhat similarly sized 51-56kD component. Species Crossreactivity: Human, baboon and green monkey. Does not crossreact with rat.
