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 and then biotinylated.

Catalog #:

500-P191Bt

Source :

Rabbits

Formulation :

A sterile filtered antibody solution was lyophilized from PBS, pH 7.2.

Stability :

The lyophilized antibody is stable for at least 2 years from date of receipt at -20⁰ C. The reconstituted antibody is stable for at least two weeks at 2-8⁰ C. Frozen aliquots are stable for at least 6 months when stored at -20⁰ C. Avoid repeated freeze-thaw cycles.

Elisa 

Direct :To detect hIL-21 by direct ELISA (using 100 μl/well antibody solution) a concentration of 0.25 – 1.0 μg/ml of this antibody is required. This biotinylated polyclonal antibody, in conjunction with compatible secondary reagents, allows the detection of at least 0.2 – 0.4 ng/well of recombinant hIL-21.
Sandwich :To detect hIL-21 by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.25 – 1.0 μg/ml of this antibody is required. This biotinylated polyclonal antibody, in conjunction with ’s Polyclonal Anti-Human IL-21 (500-P191) as a capture antibody, allows the detection of at least 0.2 – 0.4 ng/well of recombinant hIL-21.

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.
