Hydroxyproline (Hyp) and proline (Pro), which have a phenyl ring structure in type I collagen, cause the maximum UV absorption peaks to be mainly concentrated at …
Fluorescein - Wikipedia
WebSep 1, 2024 · The shape of absorption and fluorescence spectra of fluorescein in CPB and C 14 DAMO micelles is very close to that in aqueous solution, suggesting that fluorescein exists mainly as the dianion form (F 2-). Fig. 4 a shows the absorption spectra of fluorescein in water in presence of varying concentrations of AOT surfactant. … WebAs with fluorescein and carboxyfluorescein, absorption of the phenolate anion (basic) form of BCECF is red-shifted and has increased molar absorptivity relative to the protonated (acidic) form ( Figure 20.2.4 ); there is little pH-dependent shift in the fluorescence emission spectrum of BCECF upon excitation at 505 nm. sharon wickner
