Human ITGA4&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA4 and ITGB1, has a calculated MW of 111.4 kDa (ITGA4) and 83.7 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 ITGA4 subunit is composed of a heavy chain (Tyr 34 - Arg 591, calculated MW 61.1 kDa) and a light chain (Ser 592 - Thr 977, calculated MW 50.1 kDa). Consequently ITGA4 migrates as 60-70 kDa, 80-85 kDa and 135-150 kDa, and ITGB1 as 100-133 kDa respectively under reducing (R) condition due to cleavage and glycosylation.
