Novel Cyanine Dyes with Vinylsulfone Group for Labeling Biomolecules was written by Park, Jin Woo;Kim, YoungSoo;Lee, Kee-Jung;Kim, Dong Jin. And the article was included in Bioconjugate Chemistry in 2012.Formula: C13H17NO3S This article mentions the following:
Novel vinylsulfone cyanine dyes (em. 550-850 nm) were designed and synthesized for fluorescent labeling of biomols. via 1,2-addition reaction in aqueous conditions. Due to the virtue of chem. structures of both fluorophore and reactive group, these dyes could be significantly stable and reactive in various aqueous/organic conditions. A wide variety of pH, temperature, buffer concentration, and protein were tested for the optimal labeling condition. In the experiment, the researchers used many compounds, for example, 1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate (cas: 146368-07-2Formula: C13H17NO3S).
1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate (cas: 146368-07-2) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Formula: C13H17NO3S
