Dot-immunobinding assay with the globular domain of collagen type IV for antiglomerular basement membrane antibodies
1988
A dot-immunobinding assay for the detection of antiglomerular basement membrane antibodies has been developed. The globular domain NC1 of basement membrane collagen type IV was used as antigen. The assay proved to be specific, sensitive, and reproducible. Circulating antibodies in each of 12 sera from patients with florid Goodpasture's syndrome could be demonstrated, whereas sera from patients with Goodpasture's syndrome in clinical remission and various control sera showed no reactivity. The advantages of the dot-blot assay are: the usage of the purified Goodpasature target antigen NCI reduces unspecific binding of IgG; only minimal amounts of antigen are required to give a positive signal…
Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron
2013
Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…
