Extinction coefficient (ε): 200,000 L??mol??1??cm??1
Quantum yield (Φ): 0.24 | | Uses | CY7-SE is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis[1]. CY dyes are of en used for the labeling of proteins, antibodies and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction. Below, we introduce the labeling method of protein antibody labeling, which has certain reference significance[2]. | | Definition | ChEBI: A C7-cyanine dye having differentially-substituted 2-indolyl units at each end. | | References | [1] Ptaszek M.
