Methods, 2000
Expression immunoassay is a sensitive analytical method that takes advantage of coupled in vitro transcription and translation as a signal amplification technique. Essentially, the immunoassay is performed using a detection antibody that is labeled with an expressible fragment of DNA.

Methods, 2000
As a glycoprotein hormone, human chorionic gonadotropin (hCG) is not a single molecular entity. This term comprises not only the bioactive heterodimer hCG but also an array of molecular protein backbone and glycosylation variants, such as its free beta (hCGbeta) and alpha (hCGalpha) subunits and clipped, cleaved, terminally differently sialylated, and ...

Critical Reviews in Clinical Laboratory Sciences, 1990
An exciting new analytical technique based on amperometric devices used to measure immunoassays is reviewed in this article. The utility, ease, speed, simplicity, and many other advantages of performing amperometric immunoassays (AIAs) are discussed throughout the review.

Immunoassays | Luminescence immunoassays
2019Immunoassays (IAs) are analytical methods based on the specific recognition between the antigen (Ag), which molecular weight can vary in a wide range, and the variable regions of antibody (Ab), a Y shaped macromolecule composed by four polypeptide chains.

With the proliferation of immunoassays used in the clinical laboratory, we have come to realize that there are many factors which can interfere with these assays. Some of these, like exogenous radioactivity, will only interfere with one type of immunoassay--the radioimmunoassay.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1987
Abstract Immunoassays are routinely used to detect, specifically, low levels of many antigens. The trend away from the use of radioisotopic labels has resulted in a proliferation of alternative labels, many of which have electrochemical activity. The more successful of these assays have used enzyme labels, coupled with amperometric or

Fresenius' Journal of Analytical Chemistry, 2000
Immunoassays (IA) use the specific antigen antibody complexation for analytical purposes. Radioimmunoassays (RIA), fluorescence immunoassays (FIA) and enzyme immunoassays (EIA) are well established in clinical diagnostics. For the development of hand-held devices which can be used for point of care measurements, electrochemical immunoassays are ...

Chemiluminescence and immunoassays
Journal of Pharmaceutical and Biomedical Analysis, 1994The principles of chemiluminescence and the application of chemiluminescent labels and substrates in immunoassays are reviewed. Various immunoassay formats and all known classes of chemiluminescent molecules, including 1,2-dioxetanes, luminol and derivatives, acridinium esters, oxalate esters and firefly luciferins are described as well as the many ...

Immunoassay of Podophyllotoxin
Journal of Natural Products, 1993The purpose of our research was to design and develop a sensitive immunoassay for the natural Podophyllum lignan, podophyllotoxin [1], which is the precursor of the anti-cancer drugs etoposide [2] and teniposide [3]. In order to obtain a specific antiserum, bovine serum albumin and keyhole limpet hemocyanin conjugates of succinyl-podophyllotoxin [5 ...
