Cy 3 (Non-Sulfonated) (triethylamine)  (Synonyms: Cyanine3 triethylamine)

Cy 3 Non-Sulfonated (Cyanine3) triethylamine is a cyanine (Cy) dye, and a fluorescent label with green channel for protein and nucleic acid. Cy 3 Non-Sulfonated triethylamine is a fluorescent photoproduct of Cyanine5 via photoconversion upon photoexcitation. Cy 3 Non-Sulfonated triethylamine can be used to high-density single-particle tracking in a living cell without using UV illumination and cell-toxic additives (Ex=470 nm; Em=515 nm and 565 nm nm)^[1][2].

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Labeling of Protein^[2]:
1. Add protein (100 μL) to Cy 3 Non-Sulfonated triethylamine in 96 black micro-well for 50 min at 37 ℃. Incubate the cells according to your normal protocol.
2. Scan plate using BioTek and collect data with excitation wavelength of 470 nm, and emission wavelength of 515 nm and 565 nm.
