Imaging Chloride Homeostasis in Neurons
… screening, protein engineering and two-photon-imaging this thesis work led to the discovery of new chloride-sensitive GFP mutants and to the establishment of ratiometric imaging procedures for the quantitative combined imaging of intraneuronal pH and chloride. These achievements have been …

Cell biology of settlement and adhesion processes of biofouling algae
… Oregon Green BAPTA-1 and Texas Red enabled ratiometric imaging with a 5-fold greater response to Ca\(^{2+}\)-ionophores than AM-ester Ca\(^{2+}\) indicators. During settlement, zoospores exhibited both localised and diffuse increases in cytosolic calcium implying a role in secretion of the …

Wirkungen biogener Amine auf die Erregungs-Sekretions-Kopplung in der Speicheldrüse von Periplaneta americana (L.)
… Diese Experimente sollten mit der Methode des "ratiometric imaging" durchgeführt werden. Messungen mit dem Ca2+-sensitiven Fluoreszenzfarbstoff Fura-2 zeigten keinen globalen Anstieg in der intrazellulären Ca2+-Konzentration der P-Zellen. Aufgrund von Problemen mit einer schlechten Beladung der …

Charakterisierung von Transportmechanismen in der Speicheldrüse der Schabe Periplaneta americana
Die Aktivierung der Speichelsekretion erfolgt in der innervierten Speicheldrüse der Schabe Periplaneta americana durch die biogenen Amine Dopamin (DA) und Serotonin (5-HT). Die Acini der Speicheldrüse sezernieren einen Primärspeichel, der in den Ausführgängen modifiziert wird. Die durch DA und 5-HT …

Phosphate starvation alters calcium signalling in roots of Arabidopsis thaliana
… but could be reversed by P resupply. Fluorescent imaging elucidated that P-starved roots showed a normal [Ca2+]cyt response to extracellular nucleotides at the apex, but a strongly dampened [Ca2+]cyt response in distal parts of the root tip, correlating with high reactive oxygen species (ROS) …
