Sterile Filtered Blocking Reagent for Hybridization Protocols
Denhardt’s Solution (50X) is a ready-to-use blocking reagent widely used in membrane-based nucleic acid hybridization techniques such as Northern and Southern blots. This solution consists of a standardized mix of three blocking agents—1% Ficoll 400, 1% polyvinylpyrrolidone (PVP), and 1% bovine serum albumin (BSA)—which reduce nonspecific binding of nucleic acid probes to the membrane, thereby increasing hybridization signal clarity and specificity.
This UltraPure™-grade reagent is sterile-filtered, ensuring high quality and low background for sensitive applications. It is supplied as a 50X concentrate, allowing flexible dilution based on experimental requirements.
Key Features & Benefits
