Product Information
Description: Cy5 maleimide is a fluorescent dye and various cyanidin 5 (Cy5) dyes have been used to label biomolecules for fluorescent imaging and other fluorescence-based biochemical analyses. They are widely used to label peptides, proteins, and oligonucleotides, among others. The maximum excitation/emission wavelength is 651/670 nm.
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
