Published absorption spectrum (methanol) with lmax at
296 nm and 525 nm1
lmax = 475 nm, EmM = 5.76 (0.66 M glycine buffer)4
Solvent effects on absorbance:
lmax = 480 nm (water); 515 (glycerol); 520 nm (methanol): 520 nm (acetone); 532 nm (ethanol); 535 (DMSO) and 540 nm (pyridine).5 The absorbance maximum relative to water is red-shifted to longer wavelengths upon binding to nucleic acids.6,7
