Elongation factor 1-alpha
Short name= EF-1-alpha
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.
This protein is one of two protein components of a 42S RNP particle that is very abundant in previtellogenic oocytes. A major function served by 42sp50 appears to be the storage of tRNAs for later use in oogenesis and early embryogenesis. Purified 42S particles can directly transfer aminoacyl tRNA to ribosomes.
