Human/Mouse alpha 1 beta 1 (ITGA1&ITGB1) Protein, His Tag&Tag Free (MALS verified)

Integrin alpha-1/beta-1 is a receptor for laminin and collagen. The Integrin alpha-1/beta-1 and Integrin alpha-2/beta-1 integrins provide critical support for vascular endothelial growth factor signaling, endothelial cell migration, and tumor angiogenesis. It recognizes the proline-hydroxylated sequence G-F-P-G-E-R in collagen. Involved in anchorage-dependent, negative regulation of EGF-stimulated cell growth.

Human/Mouse ITGA1&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA1 and ITGB1, has a calculated MW of 130.0 kDa (ITGA1) and 83.5 kDa (ITGB1) . Subunit ITGA1 is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB1 contains no tag but a basic tail at the C-terminus. The protein migrates as >180 kDa (ITGA1) and 100-115 kDa (ITGB1) when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

-20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Native Human Collagen IV Protein at 2 μg/mL (100 μL/well) can bind Human/Mouse Integrin alpha 1 beta 1 Protein, His Tag&Tag Free (Cat. No. IN1-H52W9) with a linear range of 2-39 ng/mL (QC tested).
