Fluorescent Dye 647-I Streptavidin

Maximum Excitation/Emission wavelength: 649/664 nm

Fluorescence Dye 647-I with Streptavidin conjugate. The slight red shift in absorption spectrum makes Fluorescence Dye 647-I an optimal match to filters designed Cy5 dyes.Besides, their fluorescence is pH-independent from pH 3 to 11.

Labeling via Streptavidin for fluorescence imaging and other fluorescence-based biochemical analysis. For most fluorescent streptavidin applications, a concentration of 1-20 ug/mL is sufficient.
The optimal working dilution should be determined by the
