We used dig labelled oligonucleotides in a band-shift assay. Our problem
is, that the oligonucleotides seem to get destroyed when adding our
protein crude extract ( the signal strength of the probe without protein
is much stronger than the signal from probes with added proteins). Does
anyboby have an idea how to avoid this proplem?
