Cryoprotectant was 50% PEG just added to the buffer that it crystallised in.
It crystallised under batch.

maybe it's the cryobuffer that's the problem (you didn't mention it). you could
try to fish the crystals with minimal liquid attached by mounting them in oil
rather than a cryobuffer. or you could test the native diffraction "in situ"
(at room temperature in the drop): quite a few beamlines offer this possibility
these days.

Betreff: [ccp4bb] crystals that dont diffract :( :(
I got the most beautiful crystals I have ever seen and they don't diffract at
all. Not poor diffraction, NO diffraction. Anyone know why this could be and
how I can go about fixing it? I had three beautiful crystals and not one
diffracted. I did leave them in the drop for about 3 weeks before harvesting
and in liquid nitrogen for about a month before diffracting. Could that be a
factor? If I regrew more beautiful crystals and diffracted straight away could
that help?
