Protein-free, polymer-based blocking reagent for fast blocking without loss of sensitivity in colorimetric, chemiluminescence and fluorescence detection systems. All-in-One protocol allows completion of procedure in only 1 - 2 h.

To achieve a good signal-to-noise ratio in blotting, ELISA or other immunoassays , it is important to block nonspecific antibody binding sites. Protein based blocking solutions like skim milk or BSA solutions may not only block unspecific binding sites, but mask as well specific binding sites.
With BlueBlock, the specific binding sites remain accessible while nonspecific reactions are suppressed, thus leading to an increase in signal intensity.
