I have just read the article about colony sequencing ('Colony
Sequencing": Direct sequencing of plasmid DNA from bacterial colonies;
Biotechniques 22:412-418,. March 1997).
It looks like a very fast and relible way to sequence clones.
In the article the autors use the AmpliTaq cycle sequencing kit (Perkin-Elmer)
for radioactive colony sequencing. I was wondering if it is possible to
use normal Taq polymerase.
I can imagine that 'normal' Taq will have problems with incorporating
dideoxy nucleotides. Does somebody has experience with other
I am also interested in the experience of other people using this
This might be necessary:
The fragment I have cloned is 812 and 1133 bp large. It is ligated
into a pMOS T-vector (Amersham) and after transformation in MOSblue
cells (Amersham cloning kit) cultured on AXI-medium.
I look forward to your experiences.
