Active Recombinant Human ITGAV & ITGB8 Heterodimer Protein, His-tagged

• Cat.No.: ITGAV&ITGB8-366H
• Product Overview: Recombinant Human ITGAV & ITGB8 Heterodimer Protein, His-tagged is expressed from human 293 cells (HEK293). It contains AA Phe 31 - Val 992 (ITGAV) & Glu 43 - Arg 684 (ITGB8) (Accession # NP_002201 (ITGAV) & NP_002205 (ITGB8)). Predicted N-terminus: Phe 31 (ITGAV) & Glu 43 (ITGB8). Human ITGAV & ITGB8 Heterodimer Protein, produced by co-expression of ITGAV and ITGB8, has a calculated MW of 113.0 kDa (ITGAV) and 76.5 kDa (ITGB8). Subunit ITGAV is fused with polyhistidine tag at the C-terminus and followed by a acidic tail and subunit ITGB8 contains no tag but a basic tail at the C-terminus. The reducing (R) protein migrates as 120-130 kDa and 140-150 kDa (ITGAV) and 90-95 kDa (ITGB8) respectively due to glycosylation.
