UltraPure™ Buffer-Saturated Phenol is used in the purification of nucleic acids. The reagent, which consists of UltraPure™ Phenol that has been saturated with Tris-HCl buffer, is already buffer equilibrated to pH >7.4. When mixtures are extracted with UltraPure™ Buffer- Saturated Phenol, proteins are denatured and collect in the organic phase or at the interphase, while most nucleic acids remain in the aqueous phase. UltraPure™ Buffer-Saturated Phenol contains no preservatives. It is packaged under an inert gas in shatter-resistant, plastic-coated amber bottles.

Performance and Quality Testing: The appearance of the solution is evaluated at room temperature. No RNase or DNase activity detected.
