Details
Lambda DNA digested with SalI, 0.7% agarose, 2 cleavage sitesconventional 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.5'...G▵T C G A C...3'3'...C A G C T▵G...5' Conditions for 100% Activity1X Buffer O:50mM Tris-HCl (pH7.5 at 37°C), 10mM MgCl2, 100mM NaCl and 0.1mg/mL BSAIncubate at 37°CStorage BufferSalI is supplied in:10mM Tris-HCl (pH7.4 at 25°C),100mM KCl, 1mM DTT, 0.1mM EDTA, 0.2mg/mL BSA and 50% (v/v) glycerolLigation and RecleavageAfter 50-fold overdigestion with SalI, more than 95% of the DNA fragments can be ligated and recutMethylation EffectsDam: never overlaps — no effectDcm: never overlaps — no effectCpG: completely overlaps — blockedEcoKI: never overlaps — no effectEcoBI: never overlaps — no effectDigestion of Agarose-embedded DNAMinimum 5units of the enzyme are required for complete digestion of 1μg of agarose-embedded lambda DNA in 16hoursCompatible EndsEco88I, SmoI, XhoI Note:Low salt, high glycerol (>5%) concentrations, pH >8.0 or a large excess of enzyme may result in star activity. Supercoiled forms of pBR322 and pUC require 10-fold overdigestion with SalI to achieve complete digestion. Incubation at 25°C results in 50-75% activity.
