Research ArticleOpen accessEvery word in the titleSeparation of Guanine and Hypoxanthine with Some Ionic Liquids in RP-HPLCJ. Zheng, K. H. RowIn this paper, guanine and hypoxanthine were separated with four different ionic liquids as additives for the mobile phase using reversed phase high performance liquid chromatography (RP-HPLC). The ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIm][BF4]), 1-ethyl-3-methylimidazolium methylsulfate ([EMIm][MS]) and 1-octyl-3-methylimidazolium methylsulfate ([OMIm][MS]) were used. Guanine and hypoxanthine couldn’t be separated with many different kinds of unadjusted mobile phase, such … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,892 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleBiosensor Based on Xanthine Oxidase for Monitoring Hypoxanthine in Fish MeatHelena S. Nakatani, Luciane V. dos Santos, Cristiano P. Pelegrine et al.An amperometric enzyme electrode for the detection of hypoxanthine in fish meat is described. The hypoxanthine sensor was prepared from xanthine oxidase immobilized by covalent binding with glutaraldehyde and bovine serum albumin on a nafion-coated platinum disc electrode. The responses for hypoxanthine were obtained in 0.1 mol L-1 phosphate buffer (pH 7.0), at potential of 600mV vs Ag/AgCl. This biosensor … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 8,597 accessesView PDF Cite
