Glycine betaine/L-proline transport ATP-binding protein ProV
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Part of the ProU ABC transporter complex involved in glycine betaine and proline betaine uptake. Probably responsible for energy coupling to the transport system.
