Source:
The recombinant Human IL-2 R alpha/CD25 Protein, (amino acids Glu22-Cys213) fused with a His-Avi tag at the C-terminus, was produced in HEK 293 cells.
Molecular Weight :
The recombinant Human IL-2 R alpha/CD25 protein with the His-Avi tag at the C-terminus has a predicted MW of 24.6 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result.
Activity:
Immobilized recombinant Human IL-2 R alpha protein with the C-His-Avi tag at 0.2 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Anti-IL-2 R alpha Antibody protein with the C-hFc tag with the EC50 of 9.6 ng/ml determined by ELISA (QC Test). The affinity constant of 15.2 nM as determined in SPR assay (Biacore T200).
