Chromatography of Acidic Polysaccharides on Deae-Cellulose [PDF]

open access: yesAustralian Journal of Biological Sciences, 1962
The chromatography of polysaccharides on resinous ion-exchangers has been reported by Steiner, Neukom, and Deuel (1958). Neukom et al. (1960) later reported the chromatography of a variety of wheat and sugar-beet polysaccharides on DEAEcellulose. Only "neutral" polysaccharides could be eluted at pH 6-8 by increasing buffer and salt concentrations; acid

Purification of Rennet by DEAE-Cellulose Chromatography

open access: yesJournal of the agricultural chemical society of Japan, 1966
レンネットをDEAE-セルロースカラムに吸着させ, 0.1M燐酸緩衝液(pH 5.7)に0.1, 0.2および0.3M NaClを加えて調製した溶出液および0.1N HClで順次溶出させてレンニンを分離精製し,あわせてレンネット中に混在するペプシンをも分離し,その活性割合を測定した. (1) 0.1M燐酸緩衝液(pH 5.7)に添加するNaClの濃度を0.1Mから0.2Mに増加した溶出液で得られるFraction 3に凝乳力カが存在し, pH 6.62,イオン強度0.2の燐酸緩衝液を用いた電気泳動,沈降分析からみて均一性の高いレンニンが得られた.

Purification of phospholipase B from Penicillium notatum by hydrophobic chromatography on palmitoyl cellulose.

open access: yesJournal of Lipid Research, 1980
Phospholipase B (lysolecithin acyl-hydrolase, EC 3.1.1.5) from the mycelia of Penicillium notatum (Institute for Fermentation, Osaka, Japan; No.4640) was adsorbed from a crude solution to palmitoyl cellulose. Adsorption was efficient at pH 4 at low ionic
