Dear Crystallographers,
I was looking at some live, control HEK cells expressing just eGFP, and to my
great surprise, saw littered across the dish what appeared to be small
fluorescent needles (see attached--sorry about the size, but it's only ~1MB
total.) Can these possibly be fortuitous protein crystals? They were too small
to mount I think, and for what it's worth, parallel-transfected HeLa cells did
not have these things. But, some needles could be seen in the DIC images as
well, and the needles were only fluorescent with GFP filter sets, and not CFP,
YFP, or texas red filters. I thought of whale myoglobin crystallizing on the
decks of ships, but never thought I would see this....
