Reporter gene assays.
Reporter gene assays are versatile and sensitive methods of assaying numerous targets in high-throughput drug-screening programs. A variety of reporter genes allow users a choice of signal that can be tailored to the required sensitivity, the available detection apparatus, the cellular system employed, and the required compatibility with multiplexed assays. Promoters used to drive reporter gene...
متن کاملA specific mechanism of nonspecific inhibition.
Promiscuous small molecules plague screening libraries and hit lists. Previous work has found that several nonspecific compounds form submicrometer aggregates, and it has been suggested that this aggregate species is responsible for the inhibition of many different enzymes. It is not understood how aggregates inhibit their targets. To address this question, biophysical, kinetic, and microscopy ...
متن کاملChemiluminescence: sensitive detection technology for reporter gene assays.
A series of enzyme-activated chemiluminescence-based assays of reporter gene expression, useful in many biomedical applications, has been developed. The chemiluminescence detection systems for beta-galactosidase, beta-glucuronidase (GUS), and secreted placental alkaline phosphatase (SEAP) reporter enzymes are all based on use of 1,2-dioxetane substrates. This detection technology also permits t...
متن کاملAccelerating the pace of luciferase reporter gene assays.
Luciferase reporter gene assays have gained more importance because of their easy readout, high sensitivity and lack of environmental waste disposal problems. However, several obstacles remain that have prohibited a wider use and the implementation of this type of assay in high-throughput screening programs: (i) Measurements need to be carried out within an active enzyme reaction, and the asses...
متن کاملReporter assays for studying quadruplex nucleic acids.
DNA and RNA G-quadruplexes have gained increasing attention due to their potential role in a wide range of biological functions. The majority of functional studies characterize the influence of quadruplexes in gene expression including transcription and translation. Many of these studies have used reporter assays to elucidate the effect of quadruplexes at certain positions in promoters and untr...
