31P solid-state NMR on skeletal muscle of wild and farmed Atlantic salmon
Totland, Christian; Steinkopf, Signe Lilia; Storhaug, Lisa Tu; Seland, John Georg; Nerdal, Willy (Journal article; Peer reviewed, 2022)Over the past 50 years, 31P NMR has proven a powerful tool for obtaining information on cellular biochemistry. Here we use this technique for the first time to study intracellular phosphorous metabolites in skeletal muscle ... -
9-Acridinemethanamine and Acridine-9-Carboxaldehyde as Potential Fluorescence Lifetime pH Indicators
Totland, Christian; Thomas, Peter; Holst, Bodil; Akhtar, Naureen; Hovdenes, Jostein; Skodvin, Tore (Journal article; Peer reviewed, 2020)A significant challenge concerning the development of fluorescence lifetime (FL) based pH sensors is the paucity of fluorophores with sufficiently large FL variation with pH. Acridine is amongst the indicators with highest ... -
Effects and location of coplanar and noncoplanar PCB in a lipid bilayer: a solid-state NMR study
Totland, Christian; Nerdal, Willy; Steinkopf, Signe Lilia (Peer reviewed; Journal article, 2016-07-05)Coplanar and noncoplanar polychlorinated biphenyls (PCBs) are known to have different routes and degree of toxicity. Here, the effects of noncoplanar PCB 52 and coplanar PCB 77 present at 2 mol % in a model system consisting ... -
The use of surfactant-filled mesoporous silica as an immobilising medium for a fluorescence lifetime pH indicator, providing long-term calibration stability
Totland, Christian; Thomas, Peter; Holst, Bodil; Hovdenes, Jostein; Akhtar, Naureen; Skodvin, Tore (Peer reviewed; Journal article, 2019-11-14)Surfactant filled mesoporous silica is applied as a matrix for immobilizing the fluorescence lifetime pH-indicator acridine. We demonstrate that this type of encapsulation provides a stable and uniform chemical environment ...
