Source

Biotinylated Human IL-4 R alpha & IL-13 R alpha 1 Protein, His,Avitag&His Tag (ILR-H82W3) is expressed from human 293 cells (HEK293). It contains AA Met 26 - His 232 & Gly 22 - Thr 343 (Accession # P24394-1 & P78552-1).

Predicted N-terminus: Met 26 & Gly 22

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

Biotinylated Human IL-4 R alpha & IL-13 R alpha 1 Protein, His,Avitag&His Tag is produced by co-expression of IL-4 R alpha and IL-13 R alpha 1, has a calculated MW of 32.1 kDa (IL-4 R alpha) and 43.6 kDa (IL-13 R alpha 1). Subunit IL-4 R alpha is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) and subunit IL-13 R alpha 1 is fused with a polyhistidine tag at the C-terminus. The protein migrates as 43-55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
