Pheromone-binding protein Gp-9
Short name= PBP
Putative odorant-binding protein Gp-9
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.
Colony queen number, a major feature of social organization, is associated with worker genotype for Gp-9. Colonies are headed by either a single reproductive queen (monogyne form) or multiple queens (polygyne form). Differences in worker Gp-9 genotypes between social forms may cause differences in workers' abilities to recognize queens and regulate their numbers (By similarity).
