Analytical Biochemistry, 1993
A highly reactive amine derivatizing reagent, 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate, has been synthesized. In a rapid, one-step procedure, the compound reacts with amino acids to form stable unsymmetric urea derivatives which are readily ...

High-performance liquid chromatography of thapsigargins
Journal of Chromatography A, 1993Abstract A simple and rapid high-performance liquid chromatography method based on reversed-phase chromatography with isocratic elution [methanol—water (83:17)] and UV detection at 230 nm is described. The method permits the separation and determination of the main thapsigargins found in Thapsia garganica L. and Thapsia transtagana Brot.

Chip-based high-performance liquid chromatography for high-speed enantioseparations.
Analytical Chemistry, 2015In this work, the first high-performance chiral liquid chromatography in packed microfluidic chips is presented. The chromatographic separation was performed on a column integrated into the microfluidic glass chip and packed with the particulate chiral ...

High-Performance Liquid Chromatography of Biopolymers
Science, 1983The ability to separate biological macromolecules with good resolution on liquid chromatographic columns has depended on the development of suitable packing materials. In size exclusion chromatography, molecules are separated by size on the basis of differential permeation of the packing.
