A new method for the determination of 5,5-dimethyl-2,4-oxazolidynedione (DMO) in rabbit serum by reversed phase-HPLC with UV detection is described. The determination of DMO is performed without derivatisation. The internal standard is 5,5-diethylbarbituric acid (barbital). The method is rapid and simple with sensitivity limit of 20 ng/mL, high recovery (above 92%) and is suitable for pharmacokinetic studies.
Aim: We wanted to compare two ELISA kits for detection of IgG and IgM antibodies against Borrelia in samples taken from children with suspected neuroborreliosis.
A method for simultaneous determination of clobazam (CBZ) and its active metabolite N-desmethylclobazam (DCBZ) in various biological samples by RP-HPLC with UV detection is described. The determination of both CBZ and DCBZ is performed without derivatization. The internal standard is diazepam. The method is rapid and simple with sensitivity limits of 10 ng/mL for both CBZ and DCBZ and is suitable for routine analysis as well as for animal studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
