An enzymatic fluorometric assay for pyridoxal with high specificity and sensitivity.
نویسندگان
چکیده
An enzymatic fluorometric assay for pyridoxal with pyridoxal dehydrogenase was developed. The detection limit was about 10 pmol: the calibration curve of pyridoxal showed high linearity (r=0.993). The values obtained by this method correlated well with those by the HPLC method. The enzyme had a high specificity for pyridoxal, and thus animal samples could be directly analyzed without separation of pyridoxal 5'-phosphate by column chromatography.

The enzymatic determination of hydrogen peroxide can be accomplished with high sensitivity and specificity using N-acetyl-3, 7-dihydroxyphenoxazine (Amplex Red), a highly sensitive and chemically stable fluorogenic probe for the enzymatic determination of H2O2. Enzyme-catalyzed oxidation of Amplex Red, which is a colorless and nonfluorescent derivative of dihydroresorufin, produces highly fluor...

To date, enzymatic diagnosis of Gaucher’s disease via a fluorometric assay procedure which utilizes 4-methylumbelliferyl-P-D-glucopgranoside as a substrate has not been possible when liver serves as the source of enzyme since currently employed fluorometric procedures cannot adequately differentiate between a broad-specificity fl-glucosidase and lysosomal glucocerebrosidase activities in crude ...

We describe a PCR-based fluorometric assay for the detection of the HIV-1 genome. This technique consists of a reverse hybridization with oligonucleotide probes covalently coated onto a microtiter plate as a solid support. Several improvements to the PCR amplification and detection steps gave greater sensitivity and specificity for HIV-1 screening and resulted in a convenient and rapid techniqu...

The determination of myo-inositol trisphosphate by an enzymatic fluorometric assay is presented. The method involves the acid extraction of water-soluble inositol polyphosphates followed by separation by anion-exchange chromatography. Samples are subsequently neutralized by passage over a Dowex Cl- resin and elution with lithium chloride. Samples are then desalted with ethanol. Following dephos...

An alternatively minimizing covariant matrix error (AMCME) algorithm, newly proposed by the present authors, was applied to the simultaneous fluorometric determination of pyridoxal, pyridoxamine and 4-pyridoxic acid without loss of sensitivity. The experimental results illustrate that the profiles of spectra and concentration can be accurately resolved using the AMCME algorithm with a high sens...
