We present a procedure for the comet assay, a gel electrophoresis–based method that can be used to measure DNA damage in individual eukaryotic cells. It is versatile, relatively simple to perform and ...

A nuclear stress test helps to assess your risk of a severe cardiac event. Depending on your health, a doctor may ask you to take a treadmill test or a chemical test, which uses medications to ...

The spectrophotometric/microplate reader assay method for glutathione (GSH) involves oxidation of GSH by the sulfhydryl reagent 5,5′-dithio-bis(2-nitrobenzoic acid ...

The most probable number (MPN) bioburden test method can be a valuable tool for determining bioburden counts when the typical bioburden test methods are problematic on a particular product or when a ...

The Izod impact test fixes one end of a notched specimen in a cantilever position by means of a vice. A striker on the arm of a pendulum or similar energy carrier then strikes the specimen. The energy ...

What is a cell proliferation assay? Cell proliferation assays are in vitro techniques. Methods differ in how sensitive they are, their compatibility with high-throughput analysis, and their ...

The picture frame shear test method achieved some popularity in the early days of composite materials development when few other shear test methods existed. But as the two- and three-rail shear test ...

Bridging the gap between theory and reality, material testing transforms dense technical specifications into the physical ...

Among the first decisions to be made when initiating a composites testing program is the selection of test methods to follow. Unless performing highly customized testing, it’s usually not difficult to ...

Engineers have long used thermal-cycle testing determine the reliability of PWBs (printed wire boards). Traditionally, engineers have used thermal-cycling ovens, liquid to liquid and fluidized sand, ...
