High-Pressure Liquid Chromatography
An isocratic reversed-phase high-pressure liquid chromatographic method for the determination of six components of the teicoplanin complex in biological fluid was developed. By using fluorescence detection after precolumn derivatization with fluorescamine, the assay is specific and highly sensitive, with reproducibility studies yielding coefficients of variation ranging from 1.5 to 8.5% (at 5 t...
متن کاملHigh Pressure Liquid Chromatography Purification
Two single-stranded nucleic acid-binding proteins, UP1 and UP2, that were originally reported by Herrick and Alberts (Herrick, G., and Alberts, B. (1976) J. Biol. Chem. 251,2124-2132) have been purified to apparent homogeneity from calf thymus by high performance liquid chromatography. The amino acid sequence of UP1 (Williams, K. R., Stone, K. L., LoPresti, M. B., Merrill, B. M., and Planck, S....
متن کاملHigh-pressure liquid chromatography: separation
The high-pressure liquid chromatographic separation of ail of the known metabolites of vitamin D2 and vitamin D3 found in biological fluids has been achieved. This technique has been successfully applied to the analysis of vitamin D mixtures, purification of vitamin D metabolites, and identification of radioactive peaks. Some theoretical bases for the observed resolutions are suggested. Supplem...

متن کاملA fluorescence detector for high-pressure liquid chromatography.
We describe a fluorescence spectrophotometer adapted with a micro quartz flow cell to record the output of modern liquid chromatographs. The optical system is double beam in that the light source variations are cancelled out by a second photomultiplier, thus enhancing the sensitivity of the technique. The emission spectra may be scanned by stopping the flow in the chromatographic column and sca...
