IL-7 R alpha & IL-2 R gamma
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.
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Passed as determined by the SABA assay / HABA assay / binding ELISA.
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
