Biotinylated Human IL-7 R alpha & IL-2 R gamma Protein, His,Avitag™&Tag Free (MALS verified)

Synonyms

IL-7 R alpha & IL-2 R gamma

Source

Biotinylated Human IL-7 R alpha & IL-2 R gamma Protein, His,Avitag&Tag Free (ILA-H82W3) is expressed from human 293 cells (HEK293). It contains AA Glu 21 - Asp 239 & Leu 23 - Asn 254 (Accession # P16871-1 & P31785-1).

Predicted N-terminus: Glu 21 & Leu 23

Molecular Characterization

Biotinylated Human IL-7 R alpha & IL-2 R gamma Protein, produced by co-expression of IL-7 R alpha and IL-2 R gamma, has a calculated MW of 32.2 kDa (IL-7 R alpha) & 31.2 kDa (IL-2 R gamma). Subunit IL-7 R alpha is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) and subunit IL-2 R gamma contains no tag at the C-terminus. The protein migrates as 43-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a heterodimer.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
