endoproteinase Lys-c storage

[rebecachoy from gmail.com]

Hi all,

I have some endoproteinase lys-c in a Tris-Cl (25mM) and EDTA (1mM)
buffer at a pH of 8.5 and I need to store it for later use. Does
anyone know how to freeze it with no problems? can I use 50% glycerol
like with other proteases I've seen in the discussion group?

Thanks,

rebeca
