I am about to make some plasmids based on a vector which has the aadA
gene. I would like to know the relative merits of streptomycin and
spectinomycin. Is one better to use than the other for selection of
recombinant E.coli and Agrobacterium tumefaciens carrying these
plasmids? Are there any difficulties using these antibiotics?
Basically are there any tricks I shoudl know about?
