Abstract

A novel amino-reactive fluorescent label is presented that is based on a yellow daylight chromophore and fluorophore. Its absorption band is wide and peaks at 431 nm in water solution, thus well matching the lines of either the 375-nm and the 431-nm diode lasers and of many frequency-variable dye lasers. When conjugated to bovine serum albumin (BSA), the fluorescence peaks at 501 nm with a ...
