The Leica
TCS
SMD
FLIM
system is part of the Leica
TCS
SMD
Series.
It is a dedicated system for
FLIM
measurements. These measurements reveal information about
the direct neighborhood of molecules on the nanometer
scale.
Local conditions can determine folding
states that influence the reactivity of molecules.
FLIM
is also used for binding studies (FLIM-FRET)
and to identify natural metabolites under physiological
conditions. The
SMD
FLIM
wizard optimizes
FLIM
measurement conditions and allows the setup of
FLIM
time series or
FLIM
stacks
The
Leica TCS
SMD
Series integrates hardware and software from PicoQuant
with the high-end confocal system Leica
TCS SP5
II. Researchers can now control a complete
SMD
experiment via one interface, the
LAS
AF software
from Leica Microsystems. The coordination of different
hardware and software components for one
SMD
experiment is now a thing of the past.
Field upgrades of Leica
TCS SP5
and SP5 II confocal systems to any of the Leica
TCS
SMD
systems,
FCS,
FLIM
and
FLCS, are possible

The picture
shows 4 HeLa cells with
FRET (Alexa488 and Alexa568) only at the centrosomes
(the microtubule organizing centers of the cell):
the lifetime of Alexa488 at the centrosomes has
decreased to 2,3ns, and the lifetime of Alexa488 outside
the centrosomes is 2,7ns. The pseudo colored lifetime is
merged with the gray scaled intensity image. Courtesy of
