Recombinant Cynomolgus/Rhesus IL21R Protein, Fc-tagged
Recombinant cynomolgus IL21R (XP_005591578.1) (Met1-Pro236) was expressed with the Fc region of human IgG1 at the C-terminus. Cynomolgus and Rhesus IL21R sequences are identical.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
1. Measured by its binding ability in a functional ELISA. 2. Immobilized human IL21 at 10 μg/mL (100 μL/well) can bind Cynomolgus IL21R-Fc. The EC50 of Cynomolgus IL21R-Fc is 0.11-0.25 μg/mL.
The recombinant cynomolgus IL21R consists 458 amino acids and predicts a molecular mass of 52 kDa.
< 1.0 EU per μg of the protein as determined by the LAL method.
>90 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
