Application

Fluorescent red 751 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 751 reactive is a new fluorescent label 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.

General description

Fluorescent red 751 reactive is a new fluorescent label 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. Fluorescent red 751 reactive shows strong fluorescence (molar absorption 220 000 M-1cm-1)
