The PACT screen was developed by Janet Newman in the lab of Tassos Perrakis. This systematic screen, a pH-, anion- and cation-testing (PACT) screen, aims to decouple the components of each condition and to provide information about the protein, even in the absence of crystals, rather than cover a wide crystallization space[http://scripts.iucr.org/cgi-bin/paper?cy5025]. The PACT screen is available from Molecular Dimensions[http://www.moleculardimensions.com/us/merchant.ihtml?pid=2403&step=4] and Qiagen [http://www1.qiagen.com/Products/Protein/Crystallization/CoreScreensForInitialInvestigations/PACTSuite.aspx?ShowInfo=1] | The PACT screen was developed by Janet Newman in the lab of Tassos Perrakis.
