Removal of proteins from membranes->references

Dear Johannes,

Yes, it is possible to recover proteins blotted to either PVDF or NC.
I do it quite often to obtain small amounts of highly purified proteins.
I've listed some references below. 

In general, one seems to get higher protein recoveries
from NC but often they are slightly contaminated with small amounts of
dissolved NC-one gets less recovery from PVDF but there is far less
contamination from the membrane.

Hi,

Does anyone know if it is possible to remove proteins from a membrane
(nitrocellulose or PVDF) after the proteins have been transferred to the
membrane? I have tried boiling the membrane-fragments for 5 min in a SDS
sample buffer (125 mM Tris-HCl pH 6.8, 10% glycerol, 2.3% SDS, 5%
beta-mercaptoethanol), but this didn't seem to have any effect.

If you have any experience with this problem, please reply to
johannes at biobase.dk.
