Laboratory standards for high-resolution respirometry: towards a QCS


The aim is to develop and establish standard experimental procedures, standard protocols and a library of substrate-uncoupler-inhibitor titration (SUIT) protocols to support applications of high-resolution respirometry and O2k-Fluorometry in basic research and diagnostic assays. These represent essential developments towards a new quality control system (QCS). Current studies of mitochondrial respiratory function are characterized by an apparently arbitrary diversity of experimental procedures, lack of standardized protocols and consequently the challenge for any project to select or systematically evaluate an appropriate assay protocol addressing a specific problem (Gnaiger 2014). To fill this gap, presently available protocols will be systematically listed, their strength and limitations tested and discussed, and finally a critically selected set of standard procedures and protocols will be developed and documented in a library of protocols. This library is intended to assist in applications of the O2k-technology for the diagnosis of mitochondrial function in cells and tissues. Present limitations of inadequate approaches (Rogers et al 2011) and outdated concepts (Barrientos et al 2009) have to be overcome, providing a rationale for establishing a set of basic reference protocols.
