The Quantech™ Digital Filter Fluorometer (pictured above) is a superior solution for the life science laboratory, whether performing a simple analysis of fluorescein or a more complex FRET biological assay. It delivers accurate results and enhances the productivity of your laboratory, allowing you to generate data quickly without scanning and calculations.
Molecular beacons are single-stranded oligonucleotide hybridization probes that offer unparalleled selectivity, and, when combined with the power of fluorescence detection, are highly sensitive. Bound to a target, their fluorescence increases dramatically.
The Thermo Scientific NanoDrop™ 3300 fluorospectrometer: a multi-source fluorescence instrument for measuring samples as small as 1 µL.
The NanoDrop 3300 performs broad spectrum fluorescent analysis using a patented surface tension technology. It delivers a wide excitation range without the need for filter changes. The micro-volume capability lowers the detection limit for sample mass by more than an order of magnitude over conventional fluorometers (e.g. two pg dsDNA – the equivalent mass of a single cell). In addition, it has operational simplicity comparable to less versatile instruments, making it easier to use for those users who have limited experience with fluorescence techniques.
Application Note: Histamine in Seafood
Due to the sensitivity of the fluorescence technique, it is often used to determine the safety of food. One area where this is very important is in the determination of contamination in seafood products. Canned fish is especially prone to contamination given the production requirements. The Thermo Scientific Quantech™ digital filter fluorometer makes sensitive fluorescence measurements down to 0.1 ppm sensitivity, well suited for the FDA limit of 50 ppm… more details.
