Peijun,
You may want to consider using the cryo-negative staining protocol developed by Sacha De Carlo et al. on your specimen. We noticed that the saturated ammonium molybdate seems to mimic the high salt condition pretty well (particles that dislike high salt dissociate in the stain solution).

Subject: [3dem] EM sample in high salt
Hello all,
I have an EM specimen which only stabilizes in high salt buffer (1M NaCl). I would like to carry out cryoEM imaging at lower salt conditions. Does anyone have a good protocol to reduce salt to 100mM or less without compromising the specimen?
Thanks so much,
Best,
Peijun
