Dear Yuri, I am a big fan of paratone oil (or similar oils) for freezing the "holy" crystal. The only drawback is that after you have frozen it in the oil its a little bit hard to recover the crystal if you want to seed from it, as its somewhat sticky... Best of luck! Marc

Dear Atul, Whilst finding Se-Met conditions you could always just phase with mercury if you are lucky enough to have an accessible free Cys residue or try NaI or I3C soaks. Always worth trying if you have readily reproducible crystals… Best of luck Marc From: atul kumar mailto:atulsingh21...
