b'Qubit 4 FluorometerThe Qubit Protein BR Assay is optimized for use with the Invitrogen Qubit 4 Fluorometer. The Qubit 4 Fluorometer provides the combination of a user-friendly fluorometer and capability to run highly sensitive fluorescence-based quantitation assays. The Qubit 4 Fluorometer is a small, economical instrument designed to work seamlessly with Invitrogen Qubit assay kits for routine protein, DNA, and RNA quantitation, and RNA integrity and quality assessment. All settings and calculations are performed directly on the instrument and can be transferred by USB drive, USB cable, or by Wi-Fi. The system is simple, fast, and easy to use, yet enables consistently accurate results for subsequent applications. Only small sample volumes of 120 L are required for all assays. Multiskan SkyHigh Microplate SpectrophotometerThe Thermo Scientific Multiskan SkyHigh Microplate Spectrophotometer provides ease of use for all photometric protein quantitation measurements. The touchscreen models offer the flexibility to use the system as a stand-alone instrument, or in conjunction with Thermo Scientific SkanIt PC software. For direct 280 nm measurements, the system provides ready-made protocols for path length correction, which normalize the absorbance values of microvolumes to values measured in standard cuvettes. The colorimetric dye measurement is simple to perform with either internal user interface pre-built sessions or by downloading the pre-built session with all the data handling from the SkanIt Cloud Library.For more details, visit thermofisher.com/platereadersTest your protein research knowledge Question: Which of the following are important considerations when selecting an appropriate protein quantitation assay?A.
