Abstract
This paper describes two polyacrylamide gel fractionators. One can be easily constructed from disposable syringes and used for fractionating standard-size analytical gels. The second is more complex but can be used for fractionating miniature gels. A rapid method of preparing gel fractions for liquid-scintillation counting is also presented. The method gives high counting efficiency, does not require hydrolysis of the gel prior to counting, and allows gel fractions to be collected directly in scintillation vials.
