โœฆ Synopsis


Beneckea harveyi have been coimmobilized onto Sepharose 4B along with various other enzymes. By using the appropriate enzymes, bioluminescent assays have been developed for the following metabolites: Dghtcose, L-lactate, 6-P-ghtconate, L-malate, L-alanine, L-glutamate, NAD, and NADP. The optimal conditions for each assay have been defined. The lower limits of detection are different for each metabolite; in general, however, lo-100 pmol can be measured. Greatest sensitivity was observed with NADP, 0.2 pmol, and NAD, I pmol. The assays are rapid, reproducible, and exhibit a large concentration range in which light output is linear with respect to metabolite concentration.

A highly sensitive fluorometric method for the quantitation of cholesterol, lipid, and other hydroperoxides at the picomole level is described. The method is based on the oxidation of dichlorofluoroscin to the fluorescent dichlorofluoroscein by hydroperoxide and hematin under mild conditions. A 1:1
