✦ Synopsis

The precipitation of proteins with polyethylene glycol (PEG) of various average molecular weights was studied. it was found that the specificity of precipitation, that is the ratio of desired protein and total protein, can be improved by using PEG fractions of lower average molecular weight than the generally employed PEG 6000. Specificity increases with decreasing average molecular weight of PEG. Purification of oc-glucosidase from crude yeast extract by fractional precipitation with PEG 400 is found comparable to gel chromatography.

## Abstract This paper reports on the use of supercritical carbon dioxide to fractionate a low molecular weight, high density polyethylene into very narrow molecular weight distributions (MWDs). A simple extraction system was developed that allowed relatively trouble free extractions of the polyeth
