Used in immunoassay procedures to prevent non-specific binding on microplate surfaces. Effectively blocks residual sites on the plate after coating with capture antibodies, reducing background noise and improving assay sensitivity. Compatible with various detection systems, including colorimetric, chemiluminescent, and fluorescent methods. Ideal for sandwich ELISA, competitive ELISA, and other antibody-antigen detection formats. Helps maintain protein stability and minimizes false positives without interfering with specific antigen-antibody interactions. Suitable for both manual and high-throughput automated platforms.
