Hoefer DynaQuant Fluorometer for Quantifying dsDNA
DyNA Quant 200 is a fixed wavelength fluorometer for 365 nm excitation and 460 nm emission. The spectral characteristics are specifically designed for the detection of double-stranded DNA using the standard Hoechst 33258 dye binding assay, which minimizes interference from the presence of protein, RNA, and nucleotide contaminants. The unit is also ideal for most standard fluorescence based assays in solution, including fluorescent probe protein labeling, GUS, b-Gal, and NAD(P)H-coupled systems.
* Quantitates DNA selectively in the presence of protein, RNA and nucleotides with the Hoechst 33258 assay.
* Measures DNA accurately from 10 ng/ml to 5 g/ml, final assay concentration, in a standard 4 ml fluorometry cuvette.
* Detects down to 1 ng of DNA in 3 l with the capillary cuvette adapter accessory.
* Automatically transfers results to a computer or printer through an serial communication port.
* Uses minimal bench space with a compact footprint: 16 35 12 cm (W D H).
* Can assay enzymes such as b-glucuronidase (GUS), b-galactosidase, proteases and NAD(P)H-coupled systems.
* Power requirements: 90-260 VAC, 47-63 Hz
* Light source: Mercury lamp (expected life 5000 h)
* Excitation range: 365 nm 7 nm @ FWHM
* Emission range: 460 nm 15 nm @ FWHM
* Detector: Silicon photodiode
* Sensitivity: 10 ng/ml in standard 1 cm path cuvette (Hoechst 33258 DNA assay)
* Data output: 16 2 LCD, RS-232 at 1200 bps
* Safety certifications: CE 89/336/EEC (EMC directive) CE 73/23/EEC (LV directive) EN-61010-1 (IEC1010-1, UL3101-1, CSA22.2 1010-1)
