Analyst AD offers detection based on: Fluorescence intensity Fluorescence polarization Time-resolved fluorescence resonance energy transfer (TR-FRET) Luminescence Absorbance (epi- and trans-) AnalystÂ® AD Assay Development System is the only no-compromise, flexible system for the development of assays destined for High Throughput Screening (HTS). By sharing a common detection hardware and software system with Analyst HT (for HTS using 96- and 384-well formats), Analyst AD eliminates the need to modify and revalidate methods due to differences in detection system features and performance. Its high sensitivity and dynamic range in all modes also makes it ideal for basic research applications requiring fluorescence readout. Analyst AD enables two-wavelength assays (such as FRET) or two-method assays. Analyst AD supports 96- and 384-well formats.
