Detailní popis

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.

Highlights

  • 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 Blot
  • Restriction fragment length polymorphism (RFLP)
  • SNP

Note

For methylation sensitivity refer to product specifications.

Compatible Ends Alw21I, BseSI, Mph1103I, PstI, SduI.
Conditions for 100% Activity
  • 1X Buffer SdaI: 37 mM Tris-acetate (pH 7.0 at 37°C), 15 mM Mg-acetate, 150 mM K-acetate, and 0.1 mg/mL BSA.
  • Incubate at 37°C
Digestion of Agarose-embedded DNA Minimum 5 units of the enzyme are required for complete digestion of 1 µg of agarose-embedded lambda DNA in 16 hours.
Double Digestion Perform double digestion using DoubleDigest.
Hazardous No
Isoschizomers Search for commercial isoschizomers using REsearch.
Note Greater than 5-fold overdigestion with SdaI may result in star activity.
Storage Buffer SdaI is supplied in: 10 mM Tris-HCl (pH 7.5 at 25°C), 100 mM KCl, 1 mM DTT, 0.1 mM EDTA, 0.2 mg/mL BSA, and 50% (v/v) glycerol.
Storage Condition -20 C
