Thermo Scientific SspI restriction enzyme recognizes the AAT^ATT site and cleaves best in G buffer at 37°C. For a table of enzymatic activities, double digestion conditions, and heat inactivation of this and other restriction enzymes, see Restrictions Reaction conditions for sexual endonuclease. Note: FastDigest enzyme for rapid DNA digestion is also available.

Thermo Scientific Conventional Restriction Endonucleases are a large collection of high quality restriction enzymes optimized to function in one buffer of a five-buffer system. In addition, a universal Tango buffer is provided to facilitate double enzyme digestion. All enzymes demonstrated 100% activity under recommended buffers and reaction conditions. To ensure consistent performance, Thermo Scientific Restriction Enzyme Reaction Buffers contain premixed BSA, which enhances the stability of multiple enzymes and binds contaminants that may be present in DNA preparations.
