Description
The MULTI-CORE™ Buffer Pack contains convenient aliquots of the Promega universal restriction enzyme 10X buffer. The MULTI-CORE™ Buffer is formulated to provide simple buffering conditions for performing multiple digestions. Many Promega restriction enzymes have between 50% and 100% activity in reactions using MULTI-CORE™ Buffer.
See the table of Promega 1X Restriction Enzyme Buffer Composition below.
1X Restriction Enzyme Buffer Composition.
MULTI-CORE™ Buffer (1X) = 25mM Tris-acetate (pH 7.5 at 37°C), 100mM potassium acetate, 10mM magnesium acetate, 1mM DTT.
Notes:
For each 10°C rise in temperature between 0°C and 25°C, the pH of Tris buffers decreases 0.31 pH units.
For each 10°C rise in temperature between 25°C and 37°C, the pH of Tris buffers decreases 0.25 pH units.
All restriction enzymes are supplied with 10mg/ml Acetylated BSA. Although BSA is not absolutely required for activity, it has been shown to enhance activity of many restriction enzymes. We recommend adding BSA to all restriction digests at a final concentration of 0.1mg/ml.
