For accurate quantitation of a particular mRNA species
and to verify equal loading and transfer, it is best
to strip and reprobe the membrane with a housekeeping gene such as β actin. Membranes should be
stripped according to the manufacturers instructions. For
DuralonTM membranes, we use a boiling solution of 0.1
× SSC and 0.1% SDS. Complete removal of the probe
should be verified by exposing the membrane to X-ray film.
