Xyloglucans were isolated by sequential extraction of the cell walls of pea (Pisum sativum L. cv. Alaska) with a xyloglucan-specific endoglucanase and KOH. The xyloglucan content and xyloglucan-oligosaccharide composition were determined for fractions obtained from the elongating and non-elongating segments

The abasic site is one of the most frequent changes occurring in DNA and has been shown to be lethal and mutagenic. An abasic site in DNA can be tagged by reaction with O-4-nitrobenzylhydroxylamine (NBHA), resulting in the formation of

An improved procedure has been developed for the rapid derivatization of oligosaccharides with UV-detectable p-nitrobenzylhydroxylamine (PNB). The improved conditions used result in quantitative derivatization of neutral oligosaccharides. Sialylated oligosaccharides can also be quantitatively PNB-derivatized without detectable desialylation. Of the oligosaccharides

A new quantitative procedure for the high-performance liquid chromatographic (HPLC) resolution of human brain gangliosides employing reversed-phase chromatography is described. To provide a derivative which can be determined by UV absorption techniques, p-nitrobenzyloxyamine was coupled to the gangliosides. Derivatization involves
