Actually, UV fluorescence imaging appears to be a pretty reliable means of
discriminating protein crystals, provided your protein has Trp residue(s).

Hi there,
Since a lot of different forms of crystals shows, I am using a quick/simple
strategy to choose crystals by applying a force on the crystal against the
wall, with the nylon loop.
Some can never break apart, so they are salt crystals? The others can not
survive the force and lose
various quasi-crystalline artefacts.
Good luck,
Artem

Hi there,
Since a lot
1. Pick many representative samples from each morphological class.
2. Take as many notes about the appearance, habits, and physical
properties of each crystal that you can.
3. Screen every crystal for diffraction in a variety of cryo-
protectants, etc.
4. All protein crystals were meant to be
