Used in immunoassays to reduce non-specific binding on membranes or microplates, enabling clearer detection of target proteins. Ideal for Western blotting and ELISA workflows, it allows rapid blocking within minutes, improving assay sensitivity and reproducibility. Compatible with various detection systems, including chemiluminescent, fluorescent, and colorimetric methods. Enhances signal-to-noise ratio, reduces background, and can be used without washing steps in some protocols, saving time and increasing throughput.
