Results suggest that in standard spinner flasks growth is limited by mixing and oxygen transfer. Modifications to spinner geometry, baffling and agitator aspect ratio provided increases in growth rate and(More)
A cation exchange chromatographic purification process step was developed for the purification of human PEGylated PYY 3-36 from the PEGylation reaction mixture. In this publication we describe experiments carried out to evaluate the chromatographic performance of arginine chloride as an effective cation exchange chromatography eluent. Using arginine we(More)
