Is your RNAse inhibitor off? Are you using filter tips at all times? Do
you run the probes straight from the transcription reaction or is there
further processing first? We don't bother much with template prep. We
cut, heat kill the enzyme and precipitate. Some here don't bother with
the heat kill. And we use miniprep dna. We have no problems with yield
or stability. I would suspect either the inhibitor or introduced
contamination from somewhere (buy new stocks of ALL ingredients too).
