Liquid Chromatography/Mass Spectrometry for the Detection and Quantification of N-Acyl-l-Homoserine Lactones and 4-Hydroxy-2-Alkylquinolines

High-performance liquid chromatography (HPLC) coupled in-line with mass spectrometry (MS) permits rapid and specific identification and quantification of N -acyl-l -homoserine lactones (AHLs) and 4-hydroxy-2-alkylquinolines (HAQs

Site-directed hydroxy radical mapping of nucleosome positions in vitro

Tris-Cl pH 7.5 to a final concentration of 10 mM. Gentle agitation may be necessary (see note 5); Take desired amount of histone octamer for reagent attachment. Add 0.05 volumes of 1 M TrisCl pH 7.5. Add 50-100 fold molar excess of freshly

Immunochemical Detection of a Fluorophore Derived from the Lipid Peroxidation Product 4-Hydroxy-2-Nonenal and Lysine

of lipid peroxidation product-derived fluorophores on protein components of lipofuscin or ceroid has yet to be obtained (for review, see refs. 1 ,2 ). We have recently identified a fluorescent product formed in the reaction of Nα -acetyllsyine (NAL
