Thrombin and high salt

[Cyril Privenzentzev]

Dear Netters:
I'd like to ask does high salt (up to 1M of NaCl) affect thrombin
protease activity? I need to cleave GST-fusion protein eluted in 0.9M
NaCl, 25 mM HEPES pH=7.6, 1 mM EDTA, 0.5 mM PMSF, 1 mM DTT, 10%
glycerol. I have to get rid EDTA and PMSF, it's clear, but what about of
salt and glycerol? May be someone know optimal condition for cleavage?
Thank you in advance,
