aflatoxins are a group of fungal toxic metabolites, which are contaminated certain food commodities. elisa is one of the sensitive methods for detection of aflatoxins. preparation and stabilizing of a proper conjugated tracer for detection of aflatoxins is probably the main step for designing an elisa method. in current study, different stabilizers were applied to stabilize a newly prepared con...

We report a novel magnetic immunoassay technique using a SERS-based microdroplet sensor. The proposed method provides a rapid and sensitive assay applicable to PSA cancer markers in serum. The sensor used in this study consisted of four distinct compartments that function that act to generate microdroplets, separate immunocomplexes and supernatant solution, isolate magnetic immunocomplex drople...

A functional modification of the surface of a 96-well microplate coupled with a thin layer deposition technique is demonstrated for enhanced fluorescence-based sandwich immunoassays. The plasma polymerization technique enabling the deposition of organic thin films was employed for the modification of the well surface of a microplate. A silver layer and a plasma-polymerized film were consecutive...

By integrating photopolymerized cross-linked polyacrylamide gels within a microfluidic device, we have developed a microanalytical platform for performing electrophoresis-based immunoassays. The microfluidic immunoassays are performed by gel electrophoretic separation and quantitation of bound and unbound antibody or antigen. To retain biological activity of proteins and maintain intact immune ...

Telavancin is a semisynthetic lipoglycopeptide with a dual mechanism of action against Gram-positive pathogens. Two brief reports have suggested potential cross-reactivity of telavancin with the vancomycin particle-enhanced turbidometric immunoassay (PETIA). The purpose of this study was to evaluate several commercially available vancomycin immunoassays (fluorescence polarization [FPIA], enzyme...

Three rapid assay techniques (latex agglutination, laser nephelometry, and EMIT enzyme immunoassay) have been evaluated for serial monitoring of the serum C reactive protein (CRP) concentration in immunosuppressed patients with fever. Radial immunodiffusion assay was used as a reference method. Latex agglutination reliably distinguished between normal and raised serum CRP concentrations. Enzyme...

Immunoassay methods are widely used to screen for urinary benzodiazepines despite several reports of false-positive and false-negative results (1). False-negative results are produced for certain benzodiazepines that have no or low cross-reactivity with the immunoassay used. False-positive results were produced by four commercial immunoassays (Behring EMIT d.a.u., Behring EMIT II, Abbott FPIA, ...
