WebEthanol precipitation of PCR-produced DNA is often used as a final purification step. The following is a typical protocol starting with DNA that has already been purified by agarose gel electrophoresis (53 ): 1. Mix 1 volume of purified DNA with 3 volumes of 70% ethanol. 2. Store for 2 h at −70°C. 3. Centrifuge at 20,000 rpm for 20 min at 4°C. 4.

Webdiscovery of tris(2-carboxyethyl)phosphine (TCEP).3. TCEP selectively and completely reduces even the most stable water-soluble alkyl disulfides over a wide pH range.4 Reductions frequently require less than 5 minutes at room temperature. TCEP is non-volatile, odorless, and unlike most other reducing agents, is resistant to air oxidation. WebWith ethanol, the DNA needs to be at a higher concentration to flocculate but the salt tends to stay soluble, even at cold temperatures.
