A rapid method for desalting and concentrating dilute protein solutions using short reversed-phase columns (3-4 cm) has been described. The recovery of proteins is usually 90-100%. The method is simple and rapid and allows the desalting and concentration of protein samples simultaneously. A wide var

β¦ Synopsis
Chromatography of AMP, NAD+, or NADH on a reverse-phase C,, Porasil B column rapidly removes ammonium formate or potassium phosphate from 90% of the nucleotide. Earlier reports showed these salts could not be separated from nucleotides by conventional desalting using gel filtration.

A sensitive and specific assay for measurement of adenine nucleotides and adenosine by paired-ion high-performance liquid chromatography is described. The I,N6-ethenoderivatives of ATP (c-ATP), ADP (+ADP), AMP (c-AMP). and adenosine (c-Ado), formed by reaction with chloroacetaldehyde at 37Β°C. were s
More than 90 dierent capsicums are found all over the world. They contain capsaicinoids, which are responsible for the hot and pungent Β―avour. After extraction by a methanolΒ±water mixture (60 : 40, v/v) from capsicum oleoresins, 13 compounds were separated by analytical HPLC on a C18 Hypersil column
