Hello Martin, 

The story about Neomycin and G418 is this: 

1. The NeoR gene is coding for neomycin phosphotransferase
2. Neomycin binds to ribosomes in certain Prokaryotes
3. G418 binds ... Eukaryotes
4. Neomycin phostransferase phosphorylates both G418 and Neomycin and 
renders them inactive.
5. G418 is only effectice in Eukaryotes
6. Neomycin ... Prokaryotes. 

This all is written down nowhere. It seems to be 
common sense <GG>.  

7. Maybe those guys who are writing the catalogues are reading this 
message here and will include these hints in every catalogue.
