Milk samples were analyzed for their lactose content using flow injection analysis and incorporating immobilized beta-galactosidase or beta-galactosidase/mutarotase and glucose oxidase/peroxidase bioreactors. These enzymes were immobilized, under mild conditions, on to a 2-fluoro-1-methylpyridinium salt-activated Fractogel support. The use of a

A derivatization reagent, 2-hydrazino-1-methylpyridine, was developed for the liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) of oxosteroids. The reagent quantitatively reacted with oxosteroids at 60 degrees C within 1h and the resulting derivatives of the mono-oxosteroids provided a 70-1600-fold higher sensitivity compared

In previous studies aimed at the sequencing of peptides and proteins from the carboxy terminus, we have derivatized the C-terminus to a thiohydantoin using acetic anhydride and trimethylsilylisothiocyanate (TMS-ITC) and subsequently hydrolyzed it to form a shortened peptide capable of
