Dependence of the electrophoretic mobility of DNA in gels on field intermittency.
The electrophoretic mobility of double helical DNA in agarose and polyacrylamide gels increases as a function of time after the electric field is applied to the gel and decreases after the field is terminated. The changes are large for long (more than 10 kb) molecules. The effects of other variables are indicated.
