Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg\/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃\/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. \nGenerally, the shelf life of liquid form is 6 months at -20℃\/-80℃. The shelf life of lyophilized form is 12 months at -20℃\/-80℃.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNotes\u003c\/b\u003e: Repeated freezing and thawing is not recommended.

Can form linear polymers of orthophosphate with chain lengths up to 1000 or more. Can use GTP instead of ATP, but the efficiency of GTP is 5% that of ATP. Also exhibits several other enzymatic activities, which include:  ATP synthesis from polyP in the presence of excess ADP, general nucleoside-diphosphate kinase activity, linear guanosine 5'-tetraphosphate synthesis and autophosphorylation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: \"Identification and nucleotide sequence of a gene encoding 5'-phosphoribosylglycinamide transformylase in Escherichia coli K12.\"\nSmith J.M., Daum H.A.
