Commercial Crystallization Kits
The Crystallization Facility utilizes commercial kits from Emerald Biosystems, Hampton Research, and Qiagen. For initial screening of samples we typically recommend 4-8 screens consisting of: Crystal Screen 1-2, Index, JCSG+, PACT, PEG-ion/Cryo, SaltRx, Wizard 1-2, and AmSO4.
If you're curious about the amount of overlap between the screens below, download this (excel):
