NAP-BLOCKER™, a blocking agent containing nonanimal proteins, is free from biotin and other cross-reacting agents present in animal-source blocking agents. It ensures uniform blocking without nonspecific binding.
     NAP-BLOCKER allows improved assay sensitivity, a clean background, and a high signal-to-background ratio. Because it is nonanimal proteins, there is no cross-reaction with animal-source antigens or primary and secondary antibodies. It is supplied as a premade (2 x) solution.
