>>hi everyone.
>>how are you?
>>my question is:
>>what is the best method of purification of pcr products for sequencing?
>>could you perhaps sketch the protocol briefly?
>>hopefully someone will the take the time to help me out by answering this
>>thank you very much:)

One additional note regarding the Exo I/SAP protocol: this will work well
if you have optimized your PCR and are seeing only one band on a gel. If
you find you have multiple products on a gel, then of course you will need
to cut out your band of interest and then purify using a gel extraction
method in order to get good sequencing results. Qiagen and Millipore, for
example, have good commercial kits for gel extraction.
