Description

Application

Fluorescent red 781 reactive is an amine conjugating fluorescent biolabel that can be used for covalent coupling to proteins and other biomolecules containing primary amino groups like amino modified DNA-oligomers and amino modified biotin. Fluorescent red 781 reactive is a new fluorescent label especially well suited for the near infrared area. Extremely long wavelength fluorescence is especially well suited for applications where sample autofluorescence might be critical or penetration of tissue or other matrix is required. Fluorescence NIR 781 reactive shows strong fluorescence. This holds also for its solid state emission.
