Well I am sure there is a protocol out therte to do it correctly but remember
that when you start with template DNA, that portion is going to be cold.
Therefore you will not get the right amount of labelled probe. The random
hexamer method makes sure that ALL ( or almost all) of your DNA is
labelled . If anybody has a protocol that uses direct label integration for
making probes I would love to talk to you.
