How can we directly sequence PCR-amplified DNA from agarose.

[Wasun Chantratita]

Dear Netters
	I am now trying to directly sequence PCR-amplified DNAs by cycle 
sequencing. I was told that excess nucleotide and amplified primers can 
interfere with the sequencing reactions. Thus,  PCR-amplified DNAs must 
be purified by either a glass matrix or isopropanol precipitation. 
However, would it be possible that we can cut a DNA band from perhaps low 
MP agarose and subject to cycle sequencing directly. If yes, would you 
please provide me that protocol or reference(s).

	Many thanks in advance
