Nadh absorption
Witrynadann als NADH (bzw. NADH +H +) bezeichnet. NAD + ist nur in leicht saurer Lösung (pH 3-7) relativ stabil (bei 4°C ca. 4 Wochen). In alkalischer Lösung zersetzt es sich rasch. NADH+H + wird leicht an der Luft bzw. in Anwesenheit von Oxidationsmitteln oxidiert, dies besonders rasch in saurer Lösung (t 1/2 bei pH 3 und 25°C beträgt 15min ... Witryna28 paź 2024 · 3.3 Monitoring NADH Fluorescence. The fact that NADH was monitored by the difference in the absorption spectrum of its reduced form limited the use of that technique to the study of mitochondria in vitro, and in very thin tissue samples (e.g., muscle) or in cell suspension.
