Molecular absorptivity and quantum yield were measured as in [ 18] and [ 19].
In addition, because of the high molecular absorptivity of these proteins at visible wavelengths, they are convenient markers in such applications as gel electrophoresis, isoelectric focusing, and gel exclusion chromatography [ 9, 10].
