13:45 (GMT-8) Erich Gnaiger poster session at at BPS2023 San Diego US - Respirometric substrate-uncoupler-inhibitor titration protocols for carbohydrate and fatty acid metabolism: from heart to brain mitochondria

Abstract submission deadline for »ATSPB 2023 Hall in Tirol AT«

Add catalase when measuring Complex IV (CIV) activity in permeabilized fibers (pfi)

Pfi have a high content of iron-containing proteins, which accelerate the autoxidation of tetramethyl-p-phenylenediamine (TMPD) in the CIV assay. Catalase prevents the accumulation of H₂O₂ generated by this autoxidation.

-This can indicate fluctuations in the room temperature or electrical supply. Controlling the temperature or changing the electrical supply may resolve this problem.
