Recombinant human CD125 (IL5RA: Interleukin 5 Receptor Subunit Alpha) encompassing amino acids 21-342. The protein is fused in C-terminal with the Fc fragment of a human IgG1 followed by a C-terminal Avi-Tag. The recombinant protein was enzymatically biotinylated using the Avi-Tag and affinity purified. Constructs: CD125 (21-342(end)-Fc (lgG1)-Avi)-(Biotin)
Formulation
