Polyvinylpyrrolidone (PVP) can form complexes with phenols and alkaloids. Complex formation removes phenols and alkaloids from plant samples, thereby inhibiting any modification of proteins by them and any hindrance they may cause to spectrophotometric determination of protein content. PVP can also enhance enzyme stability.
Polyvinylpyrrolidone (PVP) is a versatile synthetic polymer that can be used in life science and biochemical research. This water-soluble polymer has a wide range of uses as a stabilizer, emulsifier, suspending agent, solubilizer, protective colloid, and complexing agent. Its protective colloid properties are particularly valuable in stabilizing proteins, enzymes, and other biological substances.
Applications
Polyvinylpyrrolidone has been used to purify glutamine synthetase from plant samples. [2] It has been used to block PVDF (polyvinylidene fluoride) membranes and avoid nonspecific binding.
Features and Benefits
Highly versatile surfactant for life science and biochemical research
Excellent solubilizer and complexing agent
