JBScreen PEG/Salt is an effective reagent kit designed for initial screening of crystallization conditions of biological macromolecules.

It comprises high-purity PEG 3350 and PEG 5000 MME, each combined with 48 different salts, thus covering a range of anions and cations most frequently used in bio-crystallography. The unique combination of the reagents allows screening of PEG versus ionic strength, ion type and pH.

Each JBScreen PEG/Salt kit contains 24 unique reagents, 10 ml each. All 96 reagents of JBScreen PEG/Salt 1-4 are also available in a pre-filled deep well block.

All reagents are prepared using chemicals of microselect grade for molecular biology and ultra-pure water, followed by sterile (0.2 µm) filtration.

Individual Conditions of all screens are available in 10 ml as well as 100 ml volumes. Please follow this link.
