purity :
Greater than 90% as determined by SDS-PAGE.
form :
Tris-based buffer, 50% glycerol
storage stability :
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. Notes: Repeated freezing and thawing is not recommended.Store working aliquots at 4°C for up to one week.

other info2 :
Tag Info: N-terminal 6xHis-SUMO-tagged
products description :
Nucleotidyltransferase that catalyzes the formation of cyclic GMP-AMP (cGAMP) from ATP and GTP. Catalysis involves both the formation of a 2', 5' phosphodiester linkage at the GpA step and the formation of a 3', 5' phosphodiester linkage at the ApG step, producing c[G (2', 5')pA (3', 5')p]. Has antiviral activity by acting as a key cytosolic DNA sensor, the presence of double-stranded DNA (dsDNA) in the cytoplasm being a danger signal that triggers the immune responses. Binds cytosolic DNA directly, leading to activation and synthesis of cGAMP, a second messenger that binds to and activates TMEM173/STING, thereby triggering type-I interferon production. cGAMP can be transferred between cells by virtue of packaging within viral particles contributing to IFN-induction in newly infected cells in a cGAS-independent but TMEM173/STING-dependent manner (PubMed:26229115).
