Biotinylated Human IL-2RB&IL-2RG Heterodimer Protein, Fc,Avitag&Fc,Avitag (ILG-H82F3) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Asp 239 (IL-2RB) & Leu 23 - Asn 254 (IL-2RG) (Accession # P14784-1 (IL-2RB) & P31785-1 (IL-2RG)).
Predicted N-terminus: Ala 27 (IL-2RB) & Leu 23 (IL-2RG)
Request for sequence蛋白结构(Molecular Characterization)
Biotinylated Human IL-2RB&IL-2RG Heterodimer Protein, Fc,Avitag&Fc,Avitag is produced by co-expression of IL-2RB and IL-2RG, has a calculated MW of 52.8 kDa (IL-2RB) and 55.3 kDa (IL-2RG). Subunit IL-2RB is fused with a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™) and subunit IL-2RG is fused with a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™). The protein migrates as 60-66 kDa and 80-90 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
