what is it that you want to demonstrate? If it is just for structure solution, would S-SAD phasing be an option? That way all you need is a crystal, probably diffracting to better than, say, 2A. And a little bit of multiplicity.

I assume this is feasible for Lysozyme whereas I don't know the diffraction qualities of proteinase K crystals.

Hi,
Could anyone give a more or less exact recipee for preparing a derivate for lysozyme or proteinase K? like what used, concentration and soak time. we'd need some data sets for a lab course only thing that really worked so far was lysozyem KI SIRAS (which however doesnt seem to be good enough for demonstration
purposes, so we need more)

Thanks very much!

best,
Tommi
