Description

General description

1-Butanol is a clear, colorless alcohol that can be used for the removal of ethidium bromide from DNA purified by CsCl gradient ultracentrifugation. It is also suitable for use in the concentration of dilute nucleic acid solutions by repeated extractions, thus improving recovery by ethanol precipitation.
