ELISA: To detect Human IL-1RA by direct ELISA (using 100 ul/well antibody solution) a concentration of 0.25-1 ug/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 Human IL-1RA. To detect Human IL-1RA by sandwich ELISA (using 100 ul/well antibody solution) a concentration of 0.25-1 ug/ml of this antibody is required. This biotinylated polyclonal antibody, in conjunction with Polyclonal Anti-Human IL-1RA (
LS-B7435) 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 ug/ml. When used in conjunction with compatible secondary reagents the detection limit for recombinant Human IL-1RA is 1.5-3 ng/lane, under either reducing or non-reducing conditions. The applications listed have been tested for the unconjugated form of this product. Other forms have not been tested.
