Biotinylated Polyclonal Antibodies

Source: Polyclonal Rabbit

Preparation: Produced from sera of rabbits immunized with highly pure recombinant Human IL-1RA. Anti-Human IL-1RA specific antibody was purified by affinity chromatography and then biotinylated.

Immunogen: E.coli derived Recombinant Human IL-1RA (PeproTech catalog# 200-01RA)

Sandwich ELISA: To detect Human IL-1RA 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-1RA (500-P209) as a capture antibody, allows the detection of at least 0.2 – 0.4 ng/well of recombinant Human IL-1RA.

Western Blot: To detect Human IL-1RA by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 μg/ml. When used in conjunction with compatible secondary reagents the detection limit for recombinant Human IL-1RA is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.

Note:

1mg will be provided as 2x500μg.
