Thermo Scientific LweI (SfaNI) restriction enzyme recognizes GCATC(5/9)^ site at 37°C, Tango buffer The cutting effect in liquid is better (isocleavage enzyme: SfaNI). For a table of enzymatic activities, double digestion conditions, and heat inactivation of this and other restriction enzymes, see Reaction conditions for restriction enzymes.

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.

Features

• Superior quality—strict quality control and industry-leading production processes
• Convenient color-coded five-buffer system
•Includes universal Tango buffer for double digestion
•Pre-mixed BSA in reaction buffer
•Multiple restriction endonuclease specificities available

< b>Applications

•Molecular cloning
•Restriction site mapping
•Genotyping
•Southern blot
•Restriction fragment length polymorphism ( RFLP)
•SNP

Note:LweI may bind to cleaved DNA. This can cause DNA band drift during electrophoresis. To avoid atypical DNA banding patterns, use 6X DNA loading dye with SDS solution for sample preparation, or heat digested DNA in the presence of SDS before electrophoresis. For efficient cleavage, at least two copies of the LweI recognition site are required. For methylation sensitivity, see product specifications.
