Changes in Fluorescence in a Frog Sartorius Muscle Following a Twitch

摘要: IN a recent publication1 it was proposed that the blue autofluorescence of living tissues may largely be due to reduced pyridine nucleotide mitochondria. An opportunity test this hypothesis is afforded by specific response intramitochondrial an increase concentration adenosine diphosphate following muscle twitch. This has been shown spectro-photometric observations cause oxidation mitochondria both in isolated mitochondria2 and intact muscles3. Thus contraction elicits nucleotide. Such required distinguish between fluorescence cytoplasmic mitochondrial nucleotides because bound forms therefore have indistinguishable maxima at 443 mµ4.
