An ELISA Lab-on-a-Chip (ELISA-LOC)

2012
Laminated object manufacturing (LOM) technology using polymer sheets is an easy and affordable method for rapid prototyping of Lab-on-a-Chip (LOC) systems. It has recently been used to fabricate a miniature 96 sample ELISA lab-on-a-chip (ELISA-LOC) by integrating the washing step directly into an ELISA plate.

Interference in ELISA

2023
ELISA is a well-established technique used worldwide to quantify analytes present in a diverse milieu of biological samplings. It is especially important to clinicians who rely on the accuracy and precision of the test to administer patient care. Those results are to be held with great scrutiny since the assay is subject to error caused by interfering ...

ELISAs for parasitologists: or lies, damned lies and ELISAs

Parasitology Today, 1993
The introduction in 1971, by Engvoll and Perlmann, of enzyme labels in immunoassays represented a significant technical advance. Their enzyme-linked immunosorbent assay (ELISA) proved to be as sensitive as radioimmunoossoys but safer to use. Since then, ELISAs have been widely used in the assay o f anti-bodies and antigens.

Competitive ELISA

2003
Enzyme-linked immunosorbent assay (ELISA) is a very useful technique for the specific and sensitive assay of certain compounds, in which suitable antibodies, monoclonal or polyclonal, to the compounds are available. The technique has found particular application in the monitoring of environmental contaminants and toxins, either studying the primarily ...

Systems in ELISA

2009
This chapter defines the terms and examines the configurations used for most applications of ELISA. Such a chapter is important because the possibilities inherent in the systems of ELISA must be understood in order to maximize their versatility in assay design. All heterogeneous systems have three basic parameters: 1.

Indirect ELISA

2015
The enzyme-linked immunosorbent assay (ELISA) is a simple and rapid technique for detecting and quantitating antibodies or antigens attached to a solid surface. Being one of the most sensitive immunoassays, ELISA offers commercial value in laboratory research, diagnostic of disease biomarkers, and quality control in various industries.

Stages in ELISA

2009
This chapter gives general information on essential practical features of ELISAs. These can be summarized as follows: 1. Adsorption of antigen or antibody to the plastic solid phase. 2. Addition of the test sample and subsequent reagents. 3. Incubation of reactants. 4. Separation of bound and free reactants by washing. 5.
