We developed an enzyme immunoassay (ELISA) for quantitation of plasma cholinesterase substance concentrations in native plasma or serum samples. The ELISA assay is based on polyclonal (rabbit) antihuman cholinesterase and a highly specific monoclonal (mouse) antibody, with a commercially available peroxidase-conjugated (rabbit) antibody directed against mouse immunoglobulins as the signal carri...
We used a miniature centrifugal analyzer in a spectrophotometric rate-measurement mode to determine the anticonvulsant drugs phenobarbital and diphenylhydantoin in serum, by use of a modified enzyme immunoassay ("EMIT", Syva Corp.) We decreased reagent cost per determination by at least sixfold by means of microscale techniques. Also, the analysis rate is increased by measuring multiple samples...
The EMIT homogeneous enzyme immunoassay for the determination of thyroxine (T4) was adapted to an automatic analyser (Type Kem-O-Mat) and compared with a conventional radioimmunoassay. Sera from 92 patients whose thyrometabolic status was being examined, and control sera with 3 different T4 concentrations were analysed by both methods. Day-to-day analyses of the control sera gave variation coef...
A comparison is made of enzyme-immunoassay and radio-immunoassay for the detection of antibody in Chagas's disease, sleeping sickness, malaria, schistosomiasis ans invasive amoebiasis. Both assays were sensitive and reproductible and gave comparable results.
The pharmacokinetics of orally administered tacrolimus were examined in six female lupus nephritis patients (mean age 43 years, range 24-55 years). Tacrolimus (3 mg) was administered after supper, and blood tacrolimus concentrations were measured just prior to dosing and 1, 2, 4, 6, 8, 12 and 24 h after administration. The maximum blood concentration (C(max)) was observed 4-8 h (mean: 6.7 h) af...
