Srfluor® Dyes

SRfluor® dyes belong to the family of squaraine rotaxane dyes which exhibit absorption and emission properties in the far-red region of the spectrum.

SRfluor® Dyes offer

•    5-20x brighter compared to Cy5, Alexa® and Atto dyes
•    More photostable compared to Cy5, Alexa® and Atto dyes
•    Sharp absorption and fluorescence emission profiles
•    Available with a range of functionalities to allow conjugation with biomolecules for in vitro and in
     vivo
 imaging
•    Other analogs with ability to label the intracellular lipid regions of cells or bind to metal ions also
      available
