Optimal scheme of assay using competitive or sandwich immunoassays
of rabbit IgG was used.
We focused on the antimetatype antibody--based immunoassay because it is the only nonconventional sandwich immunoassay
proposed so far that enables simultaneous recognition of a hapten by 2 antibodies, which could be a key advantage to develop analytically sensitive and specific immunoassays.
The mouse monoclonal antibodies were optimized for use in a sandwich immunoassay
. The monoclonal antibody 12H06 was used as a capture antibody and biotinylated monoclonal antibody 01D10 was used as a capping antibody.
MAGNETICALLY PROMPTED RAPID SANDWICH IMMUNOASSAY

Toward the limits of sandwich immunoassay
of very low molecular weight molecules.
After all, many different novel assay chemistries, reporters, and chemical reagents have been proposed for improving sandwich immunoassays
. The answer must lie in additional future testing with clinical specimens.
The aim of this project was to develop a sandwich immunoassay
to reliably measure sGPVI and validate the novel assay in a large group of patients with symptomatic coronary artery disease (CAD).
Substantial variability and bias is commonly observed in the commercial automated sandwich immunoassays
. Thorough understanding of the interferences and cross-reactivities with PTH fragments in these commercial assays is lacking (8-11).

In sandwich immunoassays
, endogenous biotin binding to streptavidin sites can block the analyteantibody-biotin complexes from binding and becoming immobilized.
The CaptSure technology allows solution-phase delivery of antibody pairs in sandwich immunoassays
, thus enabling the simultaneous formation and immobilisation of the analyte immunocomplex in a single assay incubation.
This improves sensitivity and significantly reduces overall assay times for routine sandwich immunoassays
. The system is capable of parallel processing of up to eight test samples and is compatible with a wide range of sample types including serum/plasma, CSF, and dried blood spots.
