Integrin alpha 4 beta 1, ITGA4&ITGB1

Mouse ITGA4&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA4 and ITGB1, has a calculated MW of 110.7 kDa (ITGA4) & 83.5 kDa (ITGB1). Subunit ITGA4 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 70-75 kDa, 80-90 kDa, 115-135 kDa and 140-170 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
The protein is designed as a heterodimer.
Less than 0.01 EU per μg by the LAL method / rFC method.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, 0.2 M Arginine, pH7.5 with trehalose as protectant.
