In our lab we routinely sequence ssDNA PCR products from
mitochondrial DNA using the PCR primers in the sequencing
reactions. This has worked well for us.
At this time I am trying to sequence ssDNA PCR products
generated from RT-PCR of mRNA. Although I get great looking bands
in both the RT-PCR reaction and the ss PCR reaction, when
I sequence (using the PCR primers), I get varying results.
One of the primers (5' to 3') works okay but the one in the
other direction doesn't. I get shadowy bands with lots of
backround, almost like a stuttering effect.
Has anyone else had this problem and (hopefully) found a
Thanks in advance, Marion
P.S. we use a Taq sequencing method
