Human Integrin alpha 10 beta 1 (ITGA10&ITGB1) Heterodimer Protein, His Tag&Tag Free

Human integrin alpha (10) I domain as a recombinant protein to reveal its ligand binding specificity. In general, alpha (10) I did recognize collagen types I-VI and laminin-1 in a Mg (2+) -dependent manner, whereas its binding to tenascin was only slightly better than to albumin. Alpha 10 beta 1 is a known collagen-binding I domain integrin, in addition to α1β1, α2β1 and α11β1. GROGER found in the N-terminal domain of collagens I and III, is only weakly recognised by α10β1, an important collagen receptor on chondrocytes, contrasting with the other collagen-binding integrins.

Human ITGA10&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA10 and ITGB1, has a calculated MW of 126.6 kDa (ITGA10) and 83.7 kDa (ITGB1) . Subunit ITGA10 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 130-170 kDa (ITGA10) and 105-125 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 Human Collagen I protein at 2 μg/mL (100 μL/well) can bind Human ITGA10&ITGB1 Heterodimer Protein, His Tag&Tag Free (Cat. No. IT1-H52Wa) with a linear range of 0.02-0.313 μg/mL (QC tested).
