Permeabilized tissue


Permeabilized tissue (pti, see also permeabilized muscle fibers, pfi) are mitochondrial preparations obtained by selectively permeabilizing the plasma membrane mechanically or chemically (e.g., with saponin), for the exchange of soluble molecules between the cytosolic phase and external medium, without damaging the mt-membranes.

Abbreviation: pti

Reference: MiPNet11.05; O2k-Publications: Permeabilized tissue

Experimental SOP

Addition of sample to the respirometer chamber: For permeabilized tissue, remove the Stopper, add the permeabilized tissue into the O2k-Chamber, close the chamber again.
