Dear all

I will be presenting about protein crystallography to a group of PhD-level physicists and need some images from the community.

Would anyone have high-quality images of density maps that show hydrogen atoms at
1. high and ultra-high X-ray resolution (say, about 1.2 A to about 0.5 A)
2. low or medium X-ray resolution (where H atoms are not visible) compared with neutron data (with H). Ideally these images should be from the same protein so that I can show the power of complementary beam source for the diffraction.

A side question - what is the community's preference to get deuterated samples? Is it crystal soaking or growing E. coli in deuterium?

All contributions will be credited. Thanks.
