StorageThe 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.
Application Details
Greater than 90% as determined by SDS-PAGE.

Background
Viral mimic of eIF-2-alpha that acts as a pseudosubstrate for EIF2AK2/PKR kinase. Inhibits therefore eIF-2-alpha phosphorylation by host EIF2AK2/PKR kinase and prevents protein synthesis shutoff
