I am pretty sure the work you are referring to is R. B. G. Ravelli et.
al. JSR 2007
http://dx.doi.org/10.1107/S0909049506043111
the article is open access, so anyone anywhere can click on the above
link and read it.
Basically, they used EM specimen preparation methodologies to embed a
lysozyme crystal in plastic. The radiation damage rate was greatly
reduced, but it was not zero.
Recently, I have begun to think that inorganic crystals would be a good
choice for a room-temperature diffraction standard, since they are more
rad-hard than organics. The largest unit cell I have heard of for an
inorganic is Mo2P4O15 with 441 atoms in the ASU

Don't know much more about it than that however, since I can't access
this article.

Hi All,
I heard about a way of preparing crystals - presented at the BSR recently as "Crystals to go" - which allows them to be carried at room temperature then cooled for data collection i.e. for beamline testing. Please could someone point me in the right direction for the instructions on how to do this, as I didn't get a chance to see the poster!
Thanks,
Graeme
