Bacterial capsular polysaccharides (CP) are carbohydrate polymers comprised of repeating saccharide units. Several of these CP have side chains attached to their backbone structures. The side chains may include O-acetyl, phosphate, sialic acid, and other moieties. Those moieties represent the

Currently, biotin is typically determined in Japan using a microbiological method. Such microbiological assays are sensitive, but they are not always highly specific and are also rather tedious and time-consuming. In the present study, RP-HPLC and LC-MS methods for the
Previously, following derivatization to their 2-nitrophenylhydrazide (2-NPH) derivatives, fatty acid (FA) abundances have been evaluated using high-performance liquid chromatography (HPLC). Although the method was sensitive, resolution was insufficient for many of the biologically important FAs. We have developed an enhanced

An automated assay method has been developed for the measurement of serum cholinesterase activity. The samples were prepared by an automated liquid handling unit and incubated for 9.7 min at 30 degrees C, followed by automatic injection into a colorimetric
