Determination of Antioxidant Capacity on the Thermo Scientific Varioskan LUX Multimode Reader
14 Jun 2017This application note describes a method to measure the oxygen radical absorbance capacity (ORAC) of different food and beverage samples with a fluorometric assay using the Thermo Scientific™ Varioskan™ LUX multimode microplate reader. Microplate reader handling and data analysis were controlled by the Thermo Scientific™ SkanIt™ software. We show that with the Varioskan LUX reader, determination of the antioxidant capacity of samples is very fast, sensitive and accurate.

MicroplatesMicroplates are multi-well plates used to increase the throughput of biological investigations. The number of wells microplates contain can range from 6 to 3243 wells, with the 96-well format being the most commonly used. Microplates can come tailored for a range of applications including cell culture, PCR, filtration, storage, non-binding surface, protein crystallization, as well as pre-coated, deep well and normal Standard microplates. Additionally, options for microplate colors include clear , black, white or black with clear bottom and white with clear bottom for absorbance microplate reader applications. Find the best microplates for your lab in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Microplate Readers / DetectorsMicroplate readers are used to automate the detection and analysis of labeled or label-free components in microplates during assays or live-cell monitoring. Microplate readers are generally distinguished by their mode of detection. Types include absorbance, luminescence, fluorescence intensity, fluorescence polarization, TRF / FRET and multimode microplate readers. Microplate readers deliver a high throughput of samples by reading multiple wells simultaneously, with the 96-well format the most commonly used. As a result, microplate readers are often used in the drug discovery, bioassays, research and pharmaceutical industries for screening applications. Microplate loading can also be automated, with robotic microplate stackers to increase throughput.
