High sensitivity, homogeneous particle-based immunoassay for thyrotropin (Multipact).
We describe the first homogeneous, nonradioactive, high-sensitivity assay for human thyrotropin (TSH). The assay is based on particle immunoassay techniques, wherein 800-nm particles form the basis for the immunochemistry, delivery, and the detection technologies, respectively. Our assay also is the first to involve the use of fragmented monoclonal antibodies (to eliminate serum interferences) ...
متن کاملAutomated quantification of thyrotropin by radial partition immunoassay.
We describe a radial partition enzyme immunoassay in which fully automated quantification of human thyrotropin (hTSH) takes less than 11 min. This "sandwich"-type assay involves two monoclonal antibodies, both specific for the intact hTSH molecule. The solid phase consists of tabs of glass-fiber filter paper containing a pre-immobilized monoclonal anti-hTSH antibody complexed with a goat antibo...
متن کاملA rapid, sensitive enzyme-linked immunoassay for human thyrotropin.
In this enzyme-linked immunoassay for human thyrotropin (TSH) in unextracted serum we use 96-well immunoenzymometric assay plates, first coated with polyclonal antibody to TSH, then incubated with the serum samples and reacted with mouse monoclonal antibody to human TSH. After incubation with alkaline phosphatase-labeled antibody against mouse IgG, disodium p-nitrophenyl phosphate is added and ...
متن کاملThyrotropin enzyme-immunoassay in dried blood spots: a spectrophotometric method for neonatal thyroid screening.
We describe an enzyme-immunoassay with photometric endpoint determination, suitable for the measurement of thyrotropin (TSH) in dried blood spotted on filter paper. Using reagents of a commercially available test kit provided for the measurement of thyrotropin in 200 microliter serum, we have adapted the method to the determination of thyrotropin in blood spots containing ca. 10 microliter bloo...
متن کاملChemiluminescence immunoassay of thyrotropin with acridinium-ester-labeled antibody evaluated and compared with two other immunoassays.
A new chemiluminometric immunoassay of thyrotropin (TSH) involves antibody labeled with acridinium ester ("Magic Lite System," Ciba Corning Diagnostic Corp.). The assay is rapid, with two incubations totaling 2.5 h, requires two standards per run, and takes 10 s per sample for the quantification step. Analytical performance, within- and between-run reproducibilities, and linearity were excellen...
