Western Blocker Solution
Western Blocker Solution is used to block both PVDF and nitrocellulose membranes after proteins have been transferred onto them through dot blotting or Western blotting; blocking is performed to reduce or eliminate nonspecific binding of primary or secondary antibodies.
Western Blocker Solution has been optimized for detection systems using horseradish peroxidase (HRP) conjugates; it is also compatible with alkaline phosphatase based systems.
Western Blocker Solution has been used for blocking of western blot
membranes.[1][2] It has also been used for dilution of antibodies in western blot.
• Does not inhibit weak HRP signals, as many milk-based blockers do.
• Can be used both as a blocking component and as a probing component.
• Supplied ready-to-use; no preparative step is required.
