Recombinant Bovine interleukin-21 (PBP028) detected using Rabbit anti Bovine interleukin-21 (AHP2379) as the capture reagent and Rabbit anti Bovine interleukin-21:Biotin (AHP2379B) as the detection reagent followed by Streptavidin:HRP
Recombinant Bovine interleukin-21 (IL-21) is a recombinant protein corresponding to aa 18-146 of native bovine IL-21.
Bovine interleukin-21 is a potent type I regulatory cytokine belonging to the IL-15/IL-21 family expressed by activated T-cells. Interleukin-21 is involved with the modulation of T and B cell activity along with promoting proliferation of NK cells and cytotoxic T-cells.
Purified recombinant protein - lyophilized
Reconstitute with 20 µl sterile PBS containing 0.1% carrier protein Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
