CD49d (Antigen CD49d, CD49d Antigen, CDw49d, Alpha 4 Subunit of VLA-4 Receptor, Integrin alpha IV, Integrin alpha 4, IA4, ITGA4, LPAM23, MGC90518, Very Late Activation Protein 4 Receptor Alpha 4 Subunit, VLA4, VLA-4) (Biotin)

CD49d is a ~150kD single pass type 1 transmembrane glycoprotein with seven FG-GAP repeats, characteristic of alpha integrins, in its extracellular domain. CD49d can be proteolytically cleaved to yield framents of 80 and 70kD (Hemler et al. 1987). CD49d associates with either CD29 to form VLA-4 or with Integrin beta-7 to form The Peyer patches-specific homing receptor LPAM-1, involved in the lymphocyte migration and homing to gut-associated lymphoid tissue (Sackstein 2006) through its interaction with MadCam-1, preferentially expressed on Peyer’s patch high endothelial venules and postcapillary venules in lamina propria (Briskin et al. 1997). CD49d can be used in basic studies of VLA-4 mediated adhesion and its interaction with the VCAM-1 structure and has been demonstrated to inhibit cell binding to soluble VCAM-1 (Weller et al. 1991).

Storage and Stability:
Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Note: Applications are based on unconjugated antibody.
