蛋白结构（Molecular Characterization）
Biotinylated Human ITGA7X2B & ITGB1 Heterodimer Protein, produced by co-expression of ITGA7X2B and ITGB1, has a calculated MW of 116.9 kDa (ITGA7X2B) and 86.7 kDa (ITGB1). Subunit ITGA7X2B is fused with an acidic tail but no tag at the C-terminus and subunit ITGB1 contains a basic tail at the C-terminus and followed by a polyhistidine tag and an Avi tag (Avitag™). The non-reducing (NR) protein migrates as 100-115 kDa due to glycosylation.
标记（Biotinylation）
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度（Biotin:Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

背景（Background）
Integrin alpha-7/beta-1 is the primary laminin receptor on skeletal myoblasts and adult myofibers, which is highly expressed in cardiac muscle, skeletal muscle and smooth muscle cells, and localizes to Z-disc and costamere structures. It is involved in the maintenance of the myofibers cytoarchitecture as well as for their anchorage, viability and functional integrity. Isoform Alpha-7X2B and isoform Alpha-7X1B promote myoblast migration on laminin 1 and laminin 2/4, but isoform Alpha-7X1B is less active on laminin 1 (In vitro). ITGA7 has been shown to interact with Merosin, ITGB1, FHL2 and FHL3.
