JBScreen JCSG++ is a sparse matrix screen optimized for initial screening of crystallization conditions of biological macromolecules. The screen has been formulated by researchers from the Joint Center for Structural Genomics (JCSG)[1] and from the European Genomics Consortium[2].
A core set of 66 conditions used by the JCSG for high-throughput structure determination was expanded to 96 screening conditions to round out the pH profile and include various precipitants such as succinate, malonate and formate.
When JBScreen JCSG++ is used along with JBScreen PACT++, the benefits of a sparse matrix screen can be combined with the systematic investigation of the precipitation behaviour of the protein.
