Variable large protein 7
Variable major outer membrane lipoprotein 7
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.
The Vlp and Vsp proteins are antigenically distinct proteins, only one vlp or vsp gene is transcriptionally active at any one time. Switching between these genes is a mechanism of host immune response evasion.
Cell outer membrane, Lipid-anchor
Variable large protein (Vlp) family, Alpha subfamily
