>Integrin alpha 3 beta 1
Human ITGA3&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA3 and ITGB1, has a calculated MW of 133.3 kDa (ITGA3) and 83.7 kDa (ITGB1). Subunit ITGA3 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 125-150 kDa (ITGA3) and 100-110 kDa (ITGB1) respectively due to glycosylation.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.
