Applications Notes
Active blocking of heterophilic antibody interference in immunoassays. K-Block employs blocking technology that results in higher blocking efficiency than conventional blockers and provides broad coverage against HAMA, HA and RF interferences. Proven effective for ELISA and Lateral Flow assays. Suited for double mouse monoclonal assays. RECOMMENDED CONCENTRATION: • For best performance, K-Block should be included as part of the sample or conjugate diluent, at a recommended concentration range: 0.5μg/mL – 20μg/mL (diluted samples) or 5μg/mL – 200μg/mL (non-diluted samples) .
