Fluorescence and protein folding
WebOct 13, 2024 · The folding and maturation rates of intrinsically fluorescent proteins can vary from minutes to hours and are not always well characterized. If fused to a short-lived protein, an otherwise bright protein may be quite dim, as it does not have time to mature and become fluorescent before being degraded. WebThe relationship between the dipole potential and the interaction of the mitochondrial amphipathic signal sequence known as p25 with model membranes has been studied using 1-(3-sulfonatopropyl)-4-[beta[2-(di-n-octyl-amino)-6-naphthyl]viny l] pyridinium betaine (di-8-ANEPPS) as a fluorescent probe.
