Press Release
TriStar2 – continuation of a success story
Bad Wildbad, Germany, April 2014
Berthold Technologies presents the 2nd generation of its successful multi-label microplate reader
TriStar: the TriStar² capable of these reading technologies

absorbance

fluorescence

FRET

luminescence

BRET and BRET²
TriStar2 with multiple measurement technologies employs the new patent pending optical concept
ALL-4-ONE, for the first time enabling
luminescence,
fluorescence
and
absorbance measurements with highest
respective sensitivity as known from
dedicated instruments. In comparison
to its predecessor the optics has been further improved and an improvement in detection limits in
fluorescence has been achieved

Less than 6 amol ATP per well

Less than 0.3 fmol Fluorescein per well
The instrument is characterized by a universal detector with extremely low noise for fluorescence
and luminescence measurements and it is equipped with a photo diode for absorbance readings in

addition. Furthermore optical filters can be used for luminescence measurements enabling BRET
(e.g. functional assays for GPCR research) and multi-coloured luciferase reporter gene applications.
TriStar2 can be fitted with up to 3 reagent injectors – based on the proven and most accurate JET
technology – and temperature control for the microplate compartment. Two of the injectors have
their tips in reading position enabling the measurement of extremely fast reactions. New to the
instrument is the reagent compartment placed at the front where the reagents are easily accessible
and where they can be kept cooled by the addition of crushed ice when needed. For increased
sample throughput TriStar² can integrated into lab automation systems. Special reagent mounts
provide a safe fixation of small reagent vials und ensure complete consumption of the reagents
through inclination of the vial.
Thus, TriStar² microplate reader offers a multitude of possibilities and a wide range of applications.
Measurements of enzyme activities, phagocytosis, Calcium flux, cell viability, apoptosis, immuno
assays, protein and DNA concentrations and protein-protein interactions are only a few of the many
uses of TriStar².
The unit is operated via the proven and intuitive ICE software. Single and multiple endpoint
readings are possible as well as kinetic and scanning measurements. The data are displayed in
numerical and graphical formats and may be exported into EXCEL or printed.
