4-Sulforhodamine 101 cadaverine, trifluoroacete salt

Cyanine NS succinimidyl esters are non-sulfonated cyanine dyes that can be used to label proteins, oligonucleotides and nucleic acids. Available in 3 colors, Cyanine 488NS, Cyanine 555NS,  and Cyanine 647NS are non-sulfonated versions of Cy®2, Cy®3, and Cy®5, respectively. They are designed to match by charge and molecular weight for 2D DIGE platform. Biotium offers these dyes as high quality amine-reactive succinimidyl esters.  Cyanine 488NS
