货品编号: Thermofis.ER0201
品牌:Thermofis
品名: Cfr42I (SacII)
规格: 10 U/μL
产品描述
Thermo Scientific Cfr42I (SacII) restriction enzyme recognizes CCGC^GG sites and cuts best at 37°C in B buffer
(Isoschizomers: KspI, SacII, Sfr303I, SgrBI, SstII). 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.
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
Applications • Molecular cloning • Restriction site mapping • Genotyping • Southern blotting • Restriction fragment length polymorphism (RFLP) • SNP
Note: Cfr42I activity is affected by high salt concentration. Trace amounts of sodium chloride remaining in the substrate
DNA after completion of upstream applications may inhibit enzyme activity and result in impaired DNA cleavage. Certain
sites in lambda DNA are difficult to cleave with Cfr42I, the same as with its prototype SacII. At least two copies of Cfr42I
recognition site are required for efficient cleavage.
For methylation sensitivity, refer to product specifications.
