Dear fellow researcher,
the glycoprotein we are studying appears as a doublet in western blots
after SDS-PAGE. In non denaturing PAGE (no SDS, no DTT or
2-ME) it appears as a single band, but it is no longer detectable after
elettroblotting on nitrocellulose membrane. We think this might be due
to inefficient transfert for two reasons:
a) it reacts with its probe in dot blot assays, where non denaturing
conditions are used.
b) It is still strongly detectable in the gel used for the transfert.
Any hint or suggestion would be gratefully welcomed.
