Do you include detergent artifacts in your query (even those containing protein)? If so, you will be deluged...

I'd appreciate it if people could tell me their experiences with what I would call "phantom crystals", or "ghost crystals". These are objects that display the seeming morphology of crystals (clear facets, sharp edges) but do not diffract X-rays AT ALL. I would not count objects that diffract to 30 A in this category. I mean objects that don't show a single Bragg spot.
