Hi, I have a protocol for stripping DIG labelled genomic southerns:
Soln B:0.1xssc/0.1%SDS, 200mM Tris-HCl pH7.5
1) Incubate membrane for 30 mins in soln A, at 62 C .
2) Discard A and incubate in soln B, 30 mins at 62 C.
3) Wash filter in sterile 2x SSC and store sealed at 4 C.
I have used this for stripping DIG, and isotopically labelled blots and
been able to re-probe perfectly. I have stripped and re-probed upto
three times using this method, I have heard of people stripping more but
even Hybond N deteriorates eventually. Alternative is boiling in dH2O,
but this does wear the membrane significantly and you mase lose your
