Protein instability
WebbI usually ignore the instability index in ProtParam. My protein was predicted as unstable, but it remained active after being stored at -20C for years (with glycerol, of course). Proteins can be unstable out of their native environment. They can lose activity as a result of proteolysis, aggregation, and suboptimal storage. Optimal conditions for storage depend on the specific protein, and instructions can be found on the datasheet. Please find some general guidelines below. Visa mer Lyophilization allows for more stable long-term storage; however, the protein must be reconstituted before use. There are also specific considerations that … Visa mer Storage of protein solutions at room temperature leads to protein degradation and/or inactivity, also commonly as a result of microbial growth. 1. For short … Visa mer Concentration considerations Reconstitution concentration is important for protein stability. Solutions at concentrations lower than 1 mg/mLare more prone to … Visa mer

Protein instability in wine is the appearance of an “amorphous haze or deposit” in the wine (1). Chemically, the haze is made up of complexes of proteins, polysaccharides, polyphenolics and metals (1). Normally, proteins in wine are dissolved, (coated in water molecules and not visible).
