    (2) JBScreen Pentaerythritol – Screening with Alternative Polymeric Precipitants

Pentaerythritol propoxylate and pentaerythritol ethoxylate are novel polymeric precipitants serving as cryoprotectants, as well. They differ from traditional precipitants like MPD and PEG's in size and nature, thus providing a completely different screening approach.

The successful application of pentaerythritol polymers to yield protein crystals was first described by Gulick et al.[1]. Now this class of precipitants is well-established and used for crystallizing protein complexes as well as membrane proteins. Crystals of cbb3 Cytochrome Oxidase were successfully grown using pentaerythritol ethoxylate as precipitation agent, its X-ray structure was published in Science last year[2].
