<p>Applications 1,3-Dimethyl Barbituric Acid (Urapidil Impurity 4) is a derivative of Barbituric acid (B118650). All of the barbituric acid derivatives which have been reported to have pronounced hypnotic activity are disubstituted in the 5-position.<br>References Gupta, K., et al.: Eur. J. Med.

<p>This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human Barbitues. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Barbitues. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human Barbitues in the samples is then determined by comparing the OD of the samples to the standard curve.</p>
