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 BamHI, BglII, Bsp143I, MboI, PsuI.
Conditions for 100% Activity
  • Incubation at 37°C results in 50% activity
  • Greater than 15-fold over-digestion with BclI may result in star activity
  • Assayed using lambda DNA (dam-) (#SD0021)
  • BclI is blocked by dam methylation
  • To avoid dam methylation, use a dam-, dcm- strain, such as GM2163
Double Digestion Perform double digestion using DoubleDigest.
Hazardous No
Isoschizomers Search for commercial isoschizomers using REsearch.
Storage Buffer BclI is supplied in: 10 mM Tris-HCl (pH 7.4 at 25°C), 100 mM KCl, 1 mM DTT, 1 mM EDTA, 0.2 mg/mL BSA and 50% (v/v) glycerol.
Storage Condition -20 C

Methylation Effects

  • Dam: completely overlaps - blocked.
  • Dcm: never overlaps - no effect.
  • CpG: never overlaps - no effect.
  • EcoBI: may overlap - blocked.
