Only commercially available resources were used for this study, available as detailed in the key resources table. Phosphate buffered saline (PBS) and other inorganic salts were obtained at p.A. quality (VWR). The lipids used were 2,3-dimethoxy-5-methyl-6-(farnesylfarnesyl)-1,4-benzo quinone (Q6, neat oil, extracted from Saccharomyces cerevisiae), purchased from Avanti Lipids (via Merck), Decamethyltetraconta-2,6,10,14,18,22,26,30,34,38-decaenyl]-5,6-dimethoxy3-methylcyclohexa-2,5-diene-1,4-dione (Q10), purchased from Avanti Lipids (via Merck), 1,2-Distearoyl-sn-glycero-3lipid mass concentrations of 0.1 mg/ml for Q6 and 0.25 mg/ml for DSPE. In addition Ethanol≤ ≥ ≥99.9% pure from VWR and≥ phosphoethanolamine (DSPE) as well as 1’,3’-bis[1,2-dioleoyl-sn-glycero-3-phospho] glycerol (sodium salt) (18:1, cardiolipin) were purchased from Avanti Polar Lipids. The lipids were dissolved in pure chloroform from Carl Roth (assay: 99.9%), with.
Milli-Q water (Milli-pore, TOC value 2 ppb, resistivity 18 MΩ) were used throughout for making solutions and for cleaning equipment. The defined volumes of lipid containing solutions of Q6 and DSPE, respectively, were dropped onto the water surface of an LBT (R & K, Potsdam, Germany) successively.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
