Source

Mouse ITGA2&ITGB1 Heterodimer Protein, His Tag&Tag Free (IT1-M52W3) is expressed from human 293 cells (HEK293). It contains AA Tyr 27 - Thr 1129 (ITGA2) & Gln 21 - Asp 728 (ITGB1) (Accession # Q62469-1 (ITGA2) & P09055-1 (ITGB1)).

Predicted N-terminus: Tyr 27 (ITGA2) & Gln 21 (ITGB1)

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

Mouse ITGA2&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA2 and ITGB1, has a calculated MW of 127.6 kDa (ITGA2) and 83.5 kDa (ITGB1). Subunit ITGA2 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 140-150 kDa (ITGA2) and 100-120 kDa (ITGB1) when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

Formulation

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