Relevance: TetR is the repressor of the tetracycline resistance elent; its N-terminal region forms a helix-turn-helix structure and binds DNA. Binding of tetracycline to TetR reduces the repressor affinity for the tetracycline resistance gene (tetA) promoter operator sites.

Reference: Nucleotide sequence of the repressor gene of the TN10 tetracycline resistance determinant.Postle K., Nguyen T.T., Bertrand K.P.Nucleic Acids Res. 12:4849-4863(1984)

Purity: Greater than 90% as determined by SDS-PAGE.

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.
