Retron EC67 DNA adenine methylase
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.
Methylates DNA within the sequence GATC and protects the DNA from cleavage by the restriction endonuclease MboI. May play a regulatory role in the functions of the retron.
