Thermo Scientific EcoRII restriction enzyme recognizes ^CCWGG sites and cuts best at 37°C in O 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. Isoschizomers: AjnI, BseBI, Bst2UI, BstNI, BstOI, Psp6I, PspGI.
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.

Note: At least two copies of EcoRII recognition site are required for efficient cleavage. For cleavage of DNA substrates with only one copy of recognition site MvaI, neoschizomer of EcoRII is recommended. EcoRII 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. Assayed using pBR322 DNA (dcm-). EcoRII is blocked by overlapping dcm methylation. To avoid dcm methylation, use a dam-, dcm- strain, such as GM2163.For methylation sensitivity, refer to product specifications.
