I am considering end-labelling a pBR322 hinf1 digest with DIG dUTP so I
can get a marker for Southern blotting that I am doing. I am concerned
that the single (maximum 2) incorporated DIG-dUTP will be insufficient to
give a detectable flourescent signal. Does anyone have any experience of
end labelling with such non-isotopic methods at these low levels?
I am not opposed to labelling with 35S or 32P but the development times on
film are vastly different, only 30 minutes with the DIG.
Are there any commercially available DIG markers?
I already have a number of DIG labelled primers so a DIG marker would be great.
Thnks for your time,
