VesicleControl: Software for the Vesicle Prep Pro device

VesicleControl big

Using VesicleControl, complex protocols for the Vesicle Prep Pro can be defined and visually inspected. Control of parameters such as voltage amplitude, frequency, temperature and time allow very flexible protocol design for the production of homogeneously-sized vesicles. In particular, due to the control over the temperature, it is possible to generate vesicles of homogeneous lipid distribution using lipids with different phase transition temperatures.

Testimonials & Case Studies

Dr. Eric Stava - Statement about the Vesicle Prep Pro

icon vpp   “The Vesicle Prep Pro has been of great utility in our Bioelectronics research, allowing students and researchers with limited electrophysiology background to easily form giant unilamellar vesicles (GUVs).  The electronic control lets us alter the size and density of the GUVs, and the transparent chamber allows for excellent visualization of the electro-swelling process.”

University of Wisconsin-Madison, WI, US

Dr. Marisa Rangel - Statement about the Vesicle Prep Pro and Port-a-Patch

icon vpp   icon pap   “Our planar lipid bilayers are obtained from GUVs prepared with the Nanion Vesicle Prep Pro setup. Together with the Port-a-Patch, Nanion´s state-of-the-art automated patch clamp platform, the efficiency of characterization of pore-forming peptides (and other ionophores from natural sources) in artificial bilayers has greatly increased. Both systems are straightforward and easy to use, allowing high quality, low noise, single channel recordings.”

University of Sao Paulo, Butantan Institute, Sao Paulo, Brazil, WI, US

Prof. Dr. Colin Taylor - Statement about the Port-a-Patch and Vesicle Prep Pro

icon pap   icon vpp   “We are using the Vesicle Prep Pro and Port-a-Patch in our laboratory to study recombinant channel proteins reconstituted in planar bilayers. The system is easy to use and it makes experiments very efficient. Besides the great equipment, Nanion, with their widespread expertise, is also providing excellent continuous support, helping with methodology optimization and problem solving.”

Data and Applications

GUVs - Average Diameter

p44 1 GUVicon vpp   Vesicle Prep Pro data and applications:
The Image was kindly provided of Dr. Sonderman/Prof. Behrends, University of Freiburg, Germany.

The GUVs produced with the Vesicle Prep Pro typically range from 1 – 30 μm in diameter, with an average diameter of
approximately 10 μm (60-70%).

 

Gramicidin - Rapid Internal Solution Exchange

p24 4 InternExchicon pap    Port-a-Patch and   icon vpp   Vesicle Prep Pro data and applications:

Switching of internal solutions during gramicidin recordings from a lipid bilayer was obtained within seconds. A lipid bilayer was formed using giant unilamellar vesicles. Currents were recorded at a holding potential of +150 mV. The internal solution was switched from HCl to KCl, resulting in lower channel conductance.

MscL - Pressure Clamp Experiments

p16 2 MscLicon pap   Port-a-Patch and   icon vpp   Vesicle Prep Pro data and applications:

The Port-a-Patch and the Suction Control Pro was used to study the effect of pressure on functional MscL protein reconstituted in GUVs. Using symmetrical KCl solutions, MscL gating was observed at -30 mBar and -60 mBar (holding potential + 30 mV), shown as outward currents in the data traces.

Bilayer Recordings - Low Noise
