(1) Extraction(a) TENS and PCI (equal volume)
(b) PCI
(2) Precipitation3 M sodium acetate (pH 5.2) (0.1x volume)
Ethanol (3.0x volume)
(3) Re-precipitation4 M lithium chloride

TENS: 10 mM hydroxymethyl aminomethane (Tris-HCl) (pH 7.5), 1 mM ethylenedinitrilo-tetraacetic acid (sodium EDTA) (pH 8.0), 0.1 M sodium chloride (NaCl), 1% (w/v) sodium dodecyl sulfate (SDS), 2% (w/v) polyvinylpyrrolidone (PVP)-40, and 7% (v/v) 2-mercaptoethanol.
PCI: phenol (pH 4.3): chloroform: isoamyl alcohol (1.0: 0.8: 0.2).
