Sea Block®

Sea Block® is a non-mammalian blocking buffer derived from responsibly farmed Atlantic salmon (Salmo salar). It presents an excellent alternative to traditionally used blocking buffers as a universal blocking solution that prevents non-specific binding. Sea Block® improves sensitivity and specificity of assays, offers low fluorescence to minimize background interference, and shows low cross-reactivity.
