Fw: nonradioactive overgo labelling

Hi Deanne,

overgo probes are two oligonucleotides with a complementary 3-prime overlap.
The probes are labelled using a Klenow polymerase fill in reaction with 
radioactive nucleotides.
See also for a better explanation:


It gives very good and specific hybridisation probes. But for increasing 
throughput, one might think of doing it nonradioactive, e.g. with DIG 
labelled nucleotides. I just wonder if anybody has experiences with that.
