Recombinant Protein;100UG;Mouse ITGA1&ITGB1 Heterodimer Protein, His Tag&Tag Free (IT1-M52W6) is expressed from human 293 cells (HEK293). It contains AA Phe 29 - Pro 1141 (ITGA1) & Gln 21 - Asp 728 (ITGB1) (Accession # Q3V3R4-1 (ITGA1) & P09055-1 (ITGB1)).;Mouse ITGA1&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA1 and ITGB1, has a calculated MW of 130.0 kDa (ITGA1) and 83.5 kDa (ITGB1). Subunit ITGA1 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 reducing (R) protein migrates as 150-200 kDa (ITGA1) and 90-130 kDa (ITGB1) respectively due to glycosylation.;Immobilized Human Collagen IV at 2 μg/mL (100 μL/well) can bind Mouse ITGA1&ITGB1 Heterodimer Protein, His Tag&Tag Free (Cat. No. IT1-M52W6) with a linear range of 10-78 ng/mL (QC tested).
