* measured in phosphate-buffered saline, mujumdar, r. b., ernst, l. a., mujumdar, s. r., lewis, c. j., and waggoner, a. s. (1993) bioconjugate chem. 4, 105-111.
(note: the exitation/emission wavelength and quantum yield of cy3 are changed when in a rigid microenvironment, for example in different ph, highly viscous solvents, or when conjugated to biomolecules). upon attachment to biomolecules (for example oligonucleotides), significant shifts in excitation and emission wavelength have been observed under different . cy3在不同的ph环境中，波长会有较大变化。其中本公司的cy3 se的商标名称safered，未经授权严禁使用！
