Human Integrin alpha 5 beta 1 (ITGA5&ITGB1) Heterodimer Protein, His Tag&Tag Free

Integrin alpha 5 beta 1 / Integrin α5β1, which is a major cellular receptor for the extracellular matrix protein fibronectin and plays a fundamental role during mammalian development., is composed of α5 (ITGA5/CD49e) and β1 (ITGB1/CD29) subunits. Integrins are adhesion receptors that transmit bidirectional signals across the plasma membrane. The Integrin alpha 5 beta 1 and its primary extracellular matrix ligand fibronectin (Fn) are of great biological importance.

Product Specifications

Background

Specifications

Human ITGA5&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA5 and ITGB1, has a calculated MW of 110.7 kDa (ITGA5) and 83.7 kDa (ITGB1) . Subunit ITGA5 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 non-reducing (NR) protein migrates as 130-150 kDa (ITGA5) and 100-120 kDa (ITGB1) when calibrated against Star Ribbon Pre-stained Protein Marker respectively due to glycosylation.
