Ribonucleotide analogs

[delihas at ASTERIX.BIO.SUNYSB.EDU]

	Does anyone know of a ribonucleotide analog that can be incorporated
  by T7 RNA polymerase and which will render the resulting RNA resistant to
  RNases?  I am trying to make an affinity column for an RNA binding protein
  but a pesky nuclease activity keeps co-purifying with the protein of
  interest.  I tried Rnasin and Inhibitace with little success. Any ideas?
