The PEG-Ion Series combines four different Mwt PEG’s; 30%(w/v) PEG-1000, 20%(w/v) PEG-4000, 20%(w/v) PEG-8000, or 10%(w/v) PEG-10,000 with 48 different salts. The cationic components of the salts include coverage of Ammonium, Calcium, Lithium, Potassium, Sodium, Magnesium, and Zinc. The anionic components of the salts include coverage of Acetate, Chloride, Fluoride, Formate, Iodide, Nitrate, Phosphate (mono- and di-basic), Sulfate, Tartrate, Thiocyanate, Citrate, and Isothiocyanate.

Use PEG-Ion during the coarse screening phase of biological macromolecules (proteins, nucleic acids, peptides, and combinations thereof). It can also be used in combination with buffers such as JBScreen Buffer Kits or Emerald's pH Buffer Screen to further expand the crystallization possibilities.

Individual Conditions of all screens are available in 100 ml as well as 250 ml volumes. Please follow this link.
