abberior L dyes are abberior’s long Stokes-shift dye series. The common characteristic of the dyes is an exceptional long Stokes-shift between the excitation and emission maximum. Our abberior STAR L and LIVE L dyes are designed to provide bright fluorescence for multiplexed imaging. Conjugates of the dyes show a very good solubility in aqueous buffers as PBS to allow labeling of the structures of interest with a good signal-to-noise-ratio. Our dyes are manufactured in-house by our chemist, allowing a seamlessly control of the production chain, securing a purity of over 90%.
