Blocking is a necessary step in immunoassays to prevent unwanted binding and resultant false results and high background signals. Our blocking reagents from CANDOR Bioscience saturate free binding sites on plastic or other protein-binding surfaces by covering the surface with a dense layer of molecules without gaps in the layer, effectively avoiding non-specific binding. Multiple blockers are offered:
These reagents greatly improve the sensitivity and specificity of the assay. To determine which blocker is appropriate for your application, try the Blocking Reagent Sampler Package or ELISA Blocking Reagent Sampler Package.
