Source

Human IL-21 R & IL-2 R gamma Heterodimer Protein, Fc Tag&Fc Tag (ILA-H52W9) is expressed from human 293 cells (HEK293). It contains AA Cys 20 - Pro 236 (IL-21 R) & Leu 23 - Asn 254 (IL-2 R gamma) (Accession # Q9HBE5-1 (IL-21 R) & P31785-1 (IL-2 R gamma)).

Predicted N-terminus: Cys 20 (IL-21 R) & Leu 23 (IL-2 R gamma)

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

Human IL-21 R & IL-2 R gamma Heterodimer Protein, Fc Tag&Fc Tag is produced by co-expression of IL-21 R and IL-2 R gamma, has a calculated MW of 51.5 kDa (IL-21 R) & 53.6 kDa (IL-2 R gamma). Subunit IL-21 R is fused with a human IgG1 Fc tag at the C-terminus and subunit IL-2 R gamma is fused with a human IgG1 Fc tag at the C-terminus. The protein migrates as 65 kDa and 70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
