Thermo Scientific™ PaeI (SphI) (10 U/μL)

Description

The PaeI (SphI) restriction enzyme recognizes GCATG^C sites and cuts best at 37°C in B buffer (Isoschizomers: BbuI, SphI).

Lambda DNA digested with PaeI (SphI), 0.7% agarose, 6 cleavage sites

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.

Conditions for 100% Activity:

• 1X Buffer B: 10mM Tris-HCl (pH 7.5 at 37°C), 10mM MgCl₂ and 0.1mg/mL BSA
• Incubate at 37°C

Storage Buffer:

• PaeI is supplied in: 10mM potassium-phosphate (pH 7.0 at 25°C), 50mM KCl, 1mM DTT, 0.1mM EDTA, 0.15% Triton X-100, 0.5mg/mL BSA and 50% (v/v) glycerol

Ligation and Recleavage:

• After 50-fold overdigestion with PaeI, more than 95% of the DNA fragments can be ligated and recut

Methylation Effects:

• Dam: never overlaps —no effect
