To detect hIL-17F by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.25 – 1.0 μg/ml of this antibody is required. The biotinylated polyclonal antibody (TA328242) in conjunction with the unconjugated polyclonal Anti-Human IL-17F (TA328243) as a capture antibody, allows the detection of at least 0.2 – 0.4 ng/well of recombinant hIL-17F.
