storage: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℃,-80℃. The shelf life of lyophilized form is 12 months at -20℃,-80℃. Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
background:Component of ribonuclease P, a protein complex that generates mature tRNA molecules by cleaving their 5'-ends. Also a component of RNase MRP complex, which cleaves pre-rRNA sequences.
