The Impetux team will be at the 3rd European Chemokine and Cell Migration Conference that will take place from 26 to 39 June 2019 in Salamanca, Spain. We will be there to show and explain how our turnkey optical tweezers systems designed for mechanobiology studies in living cells and 3D tissues works and how it can boost your research!

Time dependence of trap position (top), force signal (middle) and Ca2+ fluorescence signal (bottom) recorded during a membrane tether pulling experiment. The force and Ca2+ ion channel activity signals exhibit negative correlation.
Force and displacement data for two beads stimulated at frequencies of 4 Hz and 0.25 Hz. The progressive reduction of the beads displacement is in concomitancy with an increase of the applied force and loading rate.
Schematic representation of the optical tweezers experiment. A fibronectin-coated bead is trapped, brought into contact with the cell membrane and stimulated with oscillations at different frequencies.
Time dependence of trap 1 and trap 2 position (top) and force (bottom) data along the different steps of the described dual tether pulling experiment.
