most bacteria don't, but bacterial polyA plos have been isolated, for
instance by Alfred Sippel and Walter Keller. Both can be bought. Promega ?
Just look in the catalogs of several larger companies.

it is a difficult thing to do, one has to titrate the length of the tails
pretty percisely. Can't you try random priming instead ?
