Polyethylene Glycol Precipitation: Fundamentals and Recent Advances
Preparative Biochemistry and BiotechnologyDownstream processing continues to face significant bottlenecks due to current purification technologies and improvements in upstream. Chromatography systems have been the primary method for purification due to their high yields and purities. However, the use of high-titer-producing strains has highlighted limitations in chromatographic steps ...

Polyethylene glycol precipitation: proceed with care [PDF]
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2008 Two articles in this volume of the Annals demonstrate the utility of polyethylene glycol (PEG) precipitation for the detection of serum macro-analytes. In these cases, elevated aspartate aminotransferase (AST) activity was due to the enzyme being sequestered in serum as a high molecular mass (macro) enzyme complex rather than as a result of increased ...
