Thermo Scientific GsuI (BpmI) restriction enzyme recognizes CTGGAG(16/14)^ sites and cuts best at 30°C in B 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: BpmI.
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 may be present 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
Note:Incubation at 37°C results in 70% activity.
GsuI requires only Mg2+ for its activity, but is stimulated by S-adenosylmethionine. 0.01 mM S-adenosylmethionine gives a 2-fold increase in activity.
GsuI 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.
GsuI 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.
