Antigen Affinity Purified Polyclonal Antibodies

Anti-Human IL-21

Product Details

Catalogue Number: 500-P191

Source: Polyclonal Rabbit

Preparation: Produced from sera of rabbits pre-immunized with highly pure (>98%) recombinant hIL-21. Anti-Human IL-21 specific antibody was purified by affinity chromatography employing immobilized hIL-21 matrix.

Immunogen: E.coli derived Recombinant Human IL-21 (PeproTech catalog# 200-21)

Sandwich ELISA: To detect hIL-21 by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.5 - 2.0 μg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with PeproTech’s Biotinylated Anti-Human IL-21 (500-P191Bt) as a detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant hIL-21.

Anti-Human IL-21 Sandwich ELISA

Western Blot: To detect hIL-21 by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 μg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant hIL-21 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
