A new fluorometric assay method for quinolinic acid is introduced in this study. Quinolinic acid-hydrazine complex, a stable fluorescent compound, is formed after heating quinolinic acid with hydrazine at 215-220°C for 2 min. Fluorescence excitation and emission maxima of the complex are at 285 and
A new assay is described for the activity of peptidyl-tRNA hydrolase on naturally occurring peptidyl-tRNA molecules. It takes advantage of the differential binding of the tRNA and peptide moieties to DEAE paper.
