AnaSpec Introduces Industry’s First FRET-Based Thrombin Assay Kit
San Jose, CA, May 30, 2009 --(PR.com)-- AnaSpec has announced the launch of the industry’s first FRET-based thrombin assay – the SensoLyte 520 Thrombin Activity Assay Kit.
Thrombin, a serine protease, plays a central role in hemostasis by converting soluble plasma fibrinogen into an insoluble fibrin clot and by promoting platelet aggregation.1 Thrombin also influences a number of normal and pathological processes, including inflammation,2 tissue repair,3 embryogenesis,4 angiogenesis,5 and tumor invasion.6
The SensoLyte 520 Thrombin Activity Assay Kit kit employs a novel internally quenched 5-FAM/QXL 520 FRET substrate (Figure 1). Thrombin cleaves the FRET substrate into two separate fragments resulting in release of the fluorescence of 5-FAM, a green dye. Increase of fluorescence can be monitored at the commonly used excitation and emission wavelengths of 490 nm and 520 nm, respectively. The long wavelength fluorescence of 5-FAM is less interfered by the autofluorescence of components in biological samples and test compounds, resulting in a high signal to background ratio. Figure 2 shows the inhibition data.
AnaSpec also offers a shorter wavelength thrombin assay, which employs an AFC (7-amido-4-trifluoromethylcoumarin) labeled substrate, the SensoLyte AFC Thrombin Activity Assay Kit.
