Biotinylated Polyclonal Antibodies
Biotinylated Anti-Murine IL-21





 





		Preparation :
Produced from sera of rabbits pre-immunized with highly pure (>98%) recombinant mIL-21 (Murine Interleukin-21). Anti-Murine IL-21 specific antibody was purified by affinity chromatography and then biotinylated.



		Catalog #:
500-P278Bt



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


Reconstitution:
Centrifuge vial prior to opening. Reconstitute in sterile PBS containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml.



		Applications :
 



		Elisa 
Direct:To detect mIL-21 by direct ELISA (using 100 μl/well antibody solution) a concentration of 0.25 C 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 C 0.4 ng/well of recombinant mIL-21.



Sandwich:To detect mIL-21 by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.25 C 1.0 μg/ml of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech’s Polyclonal Anti-Murine IL-21 (500-P278) as a capture antibody, allows the detection of at least 0.2 C 0.4 ng/well of recombinant mIL-21.



		Western Blot 
To detect mIL-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 mIL-21 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
