DescriptionThe Thermo Scientific™ DyLight™ Dyes have absorption spectra ranging from 350 to 770nm. These reagents fluoresce over a broad pH range, are more intense than Alexa Fluor™ or Cy™ Dyes in many applications and match the output wavelengths of common fluorescence instrumentation. Additionally, the water solubility of the DyLight Reagents allows a high fluor-to-protein ratio without precipitation during conjugation.
The sulfhydryl-reactive dyes contain maleimide groups that react predominantly with free –SH groups at pH 6.5-7.5, forming a stable thioether bond. At pH 7, the maleimide group is ~1000 times more reactive toward a free sulfhydryl than to an amine.1At pH values > 7.5, reactivity toward primary amines increases and hydrolysis of the maleimide group can occur.
