Extraction, Structural Characterization and Biological Activities of Polysaccharides Derived From <i>Hericium erinaceus</i>. [PDF]
This review summarizes the methods used to extract and purify H. erinaceus polysaccharides (HEP), primarily hot water extraction and column chromatography. Structural characterization indicates that the molecular weights of HEP range from 2.1 to 75,000 kDa, with glucose as the dominant monosaccharide and β‐glycosidic bonds, notably β‐glucans with 1 → 3

Purification of Rennet by DEAE-Cellulose Chromatography
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.

Chromatography of Acidic Polysaccharides on Deae-Cellulose [PDF]
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
