GenScript Western Quick Block Kit and Western Quick Block Optimization Kit are for quick blocking of any membranes used for Dot blot and Western blot. It can also be used for quick blocking of any solid surface such as microtiter plates used for ELISA. Instead of classical one-hour blocking of the solid surface with 5–10% dry milk, this kit enables the complete blocking of the solid surface in just 5 minutes. Furthermore, Western Quick Block Kit significantly increases the Western detection sensitivity compared with dry milk blocking. And less amount of antibodies can be used to reach the same antigen detection level as using classical blocking method.
