What purpose did you have in mind? If sequencing or using only one strand as a
probe, you could use a 5' biotinylated primer on one side during the PCR.
Afterward, bind the PCR product to magnetic particles and strip off the ssDNA
using NaOH. There's a protocol in the Promega book listed in the FAQ.
