Thermo Scientific Eco57I (AcuI) restriction enzyme recognizes CTGAAG(16/14)^ sites and cuts best at 37°C in G (+SAM) buffer. See Reaction Conditions for Restriction Enzymes for a table of enzyme activity, conditions for double digestion, and heat inactivation for this and other restriction enzymes. Note: Also available as a FastDigest enzyme for rapid DNA digestion. Isoschizomers: AcuI.
Thermo Scientific conventional restriction endonucleases are a large collection of high quality restriction enzymes, optimized to work in one of the buffers of the Five Buffer System. In addition, the universal Tango buffer is provided for convenience in double digestions. All of the enzymes exhibit 100% activity in the recommended buffer and reaction conditions. To ensure consistent performance, Thermo Scientific restriction enzyme reaction buffers contain premixed BSA, which enhances the stability of many enzymes and binds contaminants that sent in DNA preparations.
Features
• Superior quality—stringent quality control and industry leading manufacturing process
• Convenient color-coded Five Buffer System
• Includes universal Tango buffer for double-digestions
• BSA premixed in reaction buffers
• Wide selection of restriction endonuclease specificities
Applications
• Molecular cloning
• Restriction site mapping
• Genotyping
• Southern blotting
• Restriction fragment length polymorphism (RFLP)
• SNP
Note: Eco57I requires only Mg2+ for its activity, but is stimulated by S-adenosylmethionine. 0.01 mM S-adenosylmethionine gives a 100-fold increase in Eco57I activity. Still, complete cleavage of some substrates with Eco57I is difficult to achieve Eco57I concentration is determined by the maximum cleavage level achieved when no change in the fragmentation pattern is observed with further enzyme increase. Low salt, high glycerol (> 5%) concentrations, pH > 8.0 or a large excess of enzyme may result in star activity. Eco57I may remain associated with the cleaved DNA. This may cause DNA band shifting during electrophoresis. To avoid atypical DNA band patterns, use the 6X DNA Loading Dye & SDS Solution for sample preparation or heat the digested DNA in the presence of SDS prior to electrophoresis.For methylation sensitivity, refer to product specifications.
