DETAILS

Description (English)

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)
