Inhibition of RNA/DNA/protein synthesis

Post by RuNkLi » Thu Nov 13, 2008 9:07 am


I want to ask if there is a way to detect inhibition of macromolecules in bacteria by antibiotics with an non radioactive method.
normally we use tritium-labelled leucine, thymidine, uridine.

I know that these radioactive precursors are very sensitive, but is there a non radioactive method?

Can someone help me in this case?

maybe you could tag them with small florochromes. No ideea if you can find one that is small enough to allow your amino acid to still be incorporporated into a nucleotide chain, and that might also present problems on tRNA loading. OK, so it's not a great idea, but if you don't want to radioactivity its the only thing I can think of
