Thermo Fisher, Q32856, Qubit™ Assay Tubes

Qubit™ Assay Tubes is designed for fluorescence-based nucleic acid and protein quantitation using a compatible Qubit Fluorometer. The tubes are thin-walled polypropylene vessels with a 500 µL capacity and are supplied as a package of 500. Their tube geometry and optical characteristics support measurements made directly in the instrument after an assay working solution and a sample have been combined. The product serves as the sample container rather than supplying an assay dye, standard, or quantitation reagent. It can be paired with compatible Qubit fluorescence assay kits for measuring double-stranded DNA, RNA, or protein using the appropriate chemistry. Consistent tubes are important to measurement performance, so tubes from the same manufacturing lot are used throughout an experiment whenever possible. This ready-to-use consumable supports repeated preparation of sample and standard tubes without transferring the reaction to a separate optical vessel. The tubes ship and store at room temperature and are intended for research workflows using the Qubit Fluorometer.
