You Searched For: Assays

An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behaviour than what can be handled by traditional chemical analysis and titration.

TMB substrate kit, Pierceâ„¢

Catalog Number: (PIER34021)
Supplier: Thermo Fisher Scientific
Description: The Pierce™ TMB Substrate Kit contains soluble TMB (3,3´,5,5´-tetramethylbenzidine) that is ideal for sensitive ELISA-based applications. TMB is a chromogenic substrate for horseradish peroxidase. Once oxidised by the enzyme, this substrate yields a blue product that absorbs at 370 nm and 652 nm. Adding sulfuric or phosphoric acid to stop the reaction changes the product to yellow that absorbs at 450 nm.

Luciferase assay system, Steady-Glo®

Catalog Number: (PROME2520)
Supplier: Promega
Description: High-throughput quantitation of firefly (<i>Photinus pyralis</i>) luciferase expression in mammalian cells is commonly performed by batch processing of 96- and 384-well plates. Steady-Glo® Luciferase Assay System is designed for this purpose of providing long-lived luminescence when added to cultured cells. The homogeneous assay provides signal half-lives of over 5 hours in commonly used cell culture media, and does not require sample preprocessing. Throughput rates of several thousand samples per hour may be achieved with high reproducibility under standard laboratory conditions.

Senescence detection kit, Calbiochem®

Catalog Number: (QIA117-1)
Supplier: Merck Millipore (Oncogene)
Description: The Calbiochem® Senescence Detection Kit is useful for the histochemical detection of senescent cells. The failure of cells to become senescent may lead to tumour progression. The mechanism of this is believed to be the increased lysosomal content of senescent cells resulting in an increase of the lysosomal enzyme β-galactosidase.
