TECAN-Ultra

Trends in biochemical screening assays seem to favor the use of multi-function PMT-based readers that allow for various MTP well densities (96, 384, and 1536 well plates), can handle a number of readout formats such as prompt fluorescence, luminescence, fluorescence polarization, time-gated fluorescence, and luminescent oxygen channeling or AlphaScreen. Examples of this type including the Perkin Elmer EnVision, TECAN-Ultra, BMG FluoStar, and LJL Analyst GT can be employed for a variety of the assay technologies described above. 

All data obtained with Tecan Ultra Evolution MTP reader. The following excitation and emission wavelengths were used EDANS and AMC 350 and 500 nm RhllO 485 and 535 nm TAMRA 535 and 595 nm PT14 405 and 450 nm. 4 = primary cleavage site confirmed by MS. AMC = aminomethylcoumarin. RhllO = rhodamine 110. yE = glutamic acid attached to RhllO via its carbonic acid in side chain. EDANS = fluorophore 5-[(2-aminoethyl)amino]naphthalene-l-sulphonic acid. DABCYL = 4-(4-dimethylaminophenylazo)benzoic acid quencher. BTN = biotin. PT14 = acridone-based fluorescence lifetime label.
