The CD29 antigen, also known as the ?-1 subunit, is common to the VLA family of integrins. When acting as a matrix receptor, the CD49d antigen binds to CS-1, an alternatively spliced domain of fibronectin. When functioning as a cell receptor, the CD49d antigen binds to the vascular cell-adhesion molecule-1 (VCAM-1). The interaction between the CD49d antigen and VCAM-1 is known to play an important role in stabilizing the adhesion of lymphocytes to endothelial cells and in mediating B-lymphocyte precursor/bone marrow stromal cell adhesion. The CD49d antigen, when associated with the ? integrin, forms a lymphocyte homing receptor for Peyer's patch, binding tothe mucosal vascular addressin MAdCAM-1. The CD49d antigen is also involved in CD3-dependent CD4+ T-lymphocyte activation via its interaction with fibronectin.

Target	CD49d
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Tested Applications	FCM
Recommended dilutions	FCM: 20 μl/1 million cells. Optimal dilutions/concentrations should be determined by the end user.
Immunogen	Tissue / cell preparation (JM leukemia line).
Purification	Affinity Chromatography
Form	Liquid
Isotype	IgG1
Conjugation	PerCP
Specificity	CD49d (Anti–VLA-α-4) recognizes the 150-kilodalton (kd) α-chain of very-late antigen (VLA)-4, a member of the integrin family of cell adhesion molecules. VLA-4, like other integrins, is a noncovalently associated heterodimeric glycoprotein composed of α and ? subunits and is involved in cell–cell and cell–extracellular matrix interactions. The ?-chain of the VLA-4 complex is the CD29 antigen, a 130-kd glycoprotein.
Storage	Store in the dark at 2-8 °C.
Molecular Weight	150 kDa
Swiss Prot	P13612
GeneID	3676
Buffer	The reagent is provided in aqueous buffered solution containing protein stabilizer, and ≤0.09% sodium Azide
Availability	Shipped within 2-3 weeks.
