Selective isolation of Vibrio cholerae neuraminidase using an immobilized N-(4-nitrophenyl)oxamic acid: Selective isolation of Vibrio cholerae neuraminidase using an immobilized N-(4-nitrophenyl)oxamic acid. Brossmer, Reinhard; Ziegler, Dietmar; Keilich, Gunda (Inst. Biochem. II, Univ. Heidelberg, Heidelberg, Ger.). Hoppe-Seyler's Z. Physiol. Chem.There are some reagents with their cas registry numbers 103-94-6 and 9012-36-6 are used in this study., 358(3), 397-400 (English) 1977. CODEN: HSZPAZ. DOCUMENT TYPE: Journal CA Section: 7 (Enzymes) N-(4-Nitrophenyl)oxamic acid was coupled with Sepharose 4B (I) contg. 1,6-diaminohexane (II) as a spacer group. This material was used as a specific adsorbent in the purifn. of V. cholerae neuraminidase (III). III was completely retarded and sepd. from the bulk of the protein when washed with buffer. A stepwise increase of NaCl concn. was necessary for a sharp elution of III. The purifn. was 10-fold, and a recovery of >90% was obtained. III is only weakly retarded on a column of II coupled with I and is not adsorbed by I. .
