Is there any reason why it should be easier (or better) to sequence
double stranded DNA in one direction, rather than the other?
I am sequencing double stranded DNA using an automated sequencer
and the TAQ dye-primer method (ABI). Using the M13-20 primer
I get great sequence data, but with the reverse primer, very
little at all is readable. Since both the primers are contained in
the PRISM (pre-mixed) componant mix, I think it is unlikely
thet the difference is due to any individual pipetting or concentration
problems. What I would like to know is if there is a "biological"
reaon behind this, or of there is a possibility that the primer kit
is at fault.
Many thanks for any replies,
