Biotinylated Anti-Human IL-4

Source: Polyclonal Rabbit 

Preparation: Produced from sera of rabbits pre-immunized with highly pure (>98%) recombinant hIL-4. Anti-Human IL-4 specific antibody was purified by affinity chromatography and then biotinylated. 

Immunogen: E.coli derived Recombinant Human IL-4 

Sandwich ELISA: To detect hIL-4 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 PeproTech’s Polyclonal Anti-Human IL-4 (500-P24) as a capture antibody, allows the detection of at least 0.2 – 0.4 ng/well of recombinant hIL-4. 

Western Blot: To detect hIL-4 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-4 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
