I would like to construct a plasmid,which has no antibiotic resistance
gen. Instead I would like to integrate something else (DNA-sequence,
small gene, etc.) for convinient selection of positive clones. Due to the
fact that I want to keep my plasmid as small as possible, the
selection-marker / sequence should also be as small as possible.
I would appreciate any ideas/suggestions on that particiular case.
Plaese e-mail your ideas to ahabel at pasteur.fr
Thanks in advance :-)
