EverFluor 650/665-X, SE is an amine-reactive, non-ionic, red-fluorescent dye for synthesis of deep-red fluorescent biomolecules. EverFluor 650/665 dye is optimally excited at 646 nm and is relatively insensitive to environmental and pH changes. The SE reactive group is ideal for reactions with primary amines on peptides, proteins, modified nucleotides, biopolymers and other amine-containing biomolecules. The seven-atom spacer between the dye and it’s point of attachment may reduce interactions of the dye and the biomolecule to which it has reacted. The resulting EverFluor 650/665-labeled conjugates are brightly fluorescent in both aqueous and lipid environments.  .
