BP003670: Cynomolgus IL-21R Protein with the C-His Tag
Source: The recombinant Cynomolgus IL-21R Protein, (amino acids Cys41-Gly254) fused with a His tag at the C-terminus, was produced in HEK 293 cells.
Molecular Weight:The recombinant Cynomolgus IL-21R protein with the His tag at the C-terminus has a predicted MW of 25.70 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result.
Activity: Immobilized recombinant Human IL-21 protein with the C-His tag at 2 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Cynomolgus IL-21R protein with the C-His tag with the EC50 of 34.3 ng/ml determined by ELISA.
Purity: >95% by SEC-HPLC and SDS-PAGE under reducing conditions.
Endotoxin Level: Less than 1 EU per ug of protein as determined by LAL method.
Formulation: Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution: It is recommended to reconstitute the lyophilized recombinant Cynomolgus IL-21R Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening.
Shipping: The recombinant Cynomolgus IL-21R Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 week, 2 to 8°C under sterile conditions after reconstitution.
6 months, -20 to -70°C under sterile conditions after reconstitution.
