Prof. Dr. Armin Kargol - Statement about the Port-a-Patch

   “Nanion’s Port-a-Patch is an excellent instrument for research labs working with undergraduate students. Manual patch-clamping methods depend to a large extend on the skills of the operator. They require long training periods. For a typical undergraduate student it takes over a year to learn patch-clamping. Port-a-Patch reduces that time to only weeks and the most difficult part is to understand the software that controls the instrument. This allows undergraduate students to actively participate in real research projects.”

Prof. Dr. Carlos Villalobos - Statement about the Port-a-Patch

   “We have used Nanion´s Port-a-patch for recording endogenous Icrac, the small calcium-release activated currents that are becoming very important in cell fate and cancer hallmarks. In addition, measurements were carried out in primary cultures of human, coronary, vascular-smooth muscle cells, a very difficult cell type to patch, and several normal and tumoral, epithelial cells. In the beginning I was very skeptical, because the currents are extremely small. However, the results were excellent and clear cut. It is possible to investigate the pharmacology and molecular biology of these channels during the phenotypic switches related to transdifferentiation, aging or tumorogenesis”.

Both systems are straightforward and easy to use, allowing high quality, low noise, single channel recordings.”
