Technology
A type of electrophoresis that uses a matrix of highly purified agar to separate large molecules.
Technology
A spectrometric method that determines the type and concentration of metal elements in a sample, based upon the principle that each elemental metal absorbs a particular wavelength of ultraviolet light when exposed to heat.
Technology
A type of ELISA assay that uses a reference antigen to competitively bind labeled antibody against an antigen of interest. The strength of the signal interference caused by antibody bound to the reference antigen is used to determine the concentration of the antigen of interest.
Technology
A type of polymerase chain reaction technique in which the sample is fractionated, within which individual PCR reactions occur in each fraction.
Technology
A type of homogenous immunoassay in which sample is applied to a reagent mixture of enzyme-labeled ligand, antibody, and substrate. Substrate binding to enzyme leads to inactivation and unlabeled-ligand in the sample can be quantified by colorimetric analysis.
Technology
Fluorescent spectroscopy or fluorometry is a type of electromagnetic spectroscopy used for analyzing fluorescent spectra. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes them to emit light of a lower energy, typically, but not necessarily, visible light.
Technology
A type of chromatography assay in which an antibody-conjugate is passed over an immobilized antigen, giving a visual indication of positive or negative result.
Technology
A type of gel electrophoresis in which charged molecules travel through a pH gradient. The molecules will come to stop at the point where the net charge on the molecule is equal to that of the surrounding gel.
Technology
A type of chromatography in which separation of a mixture is achieved by passing a sample in a stream of liquid solvent through some form of material that will provide resistance by virtue of chemical interactions between the components of the sample and the material.
Technology
A type of nucleic acid amplification test in which sample DNA is exposed to a single temperature in the presence of multiple sets of primers and a polymerase with replication and high strand displacement activity. This test negates the need for thermal cyclers and may be a low cost alternative to PCR.
Technology
A type of enzyme immunoassay that uses antigen-coated microparticles as a substrate for antibody binding.
Technology
A type of high-throughput, multiplex PCR method used to determine abnormal DNA copy number changes of up to 50 genomic DNA or RNA sequences with a single pair of PCR primers. It is frequently used in the detection of genetic aberrations in tumors, and can distinguish sequences differing in only a single nucleotide.
