Complex I stability in LMNG. The overlaid size exclusion chromatograms for samples of ovine complex I purified in LMNG, freeze-thawed in liquid nitrogen in 30% glycerol buffer, exchanged into low glycerol buffer (10%), containing 0.05% LMNG, concentrated to ∼3.5 mg/ml, and incubated for 5 days at either room temperature or 4 °C are shown. mAU, milli-absorption units.
