Recombinant Human Integrin alpha 5 beta 1 (ITGA5&ITGB1) Heterodimer Protein, His Tag&Tag Free, 100 µg

Background
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.

Source
Recombinant Human ITGA5&ITGB1 Heterodimer Protein, His Tag&Tag Free (IT1-H52W5) is expressed from human 293 cells (HEK293). It contains AA Phe 42 - Tyr 995 (ITGA5) & Gln 21 - Asp 728 (ITGB1) (Accession # P08648-1 (ITGA5) & P05556-1 (ITGB1)).
Predicted N-terminus: Phe 42 (ITGA5) & Gln 21 (ITGB1)

Molecular Characterization
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) respectively due to glycosylation.

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>95% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.
