Cy2

CY is the abbreviation of Cyanine, the classic Cyanine dyes contain two nitrogen-containing heterocyclic rings, the molecule contains a conjugated chain composed of methyl Chuan (CH) n, n can be odd or even. This characteristic can significantly affect the electronic structure of their electronic base state of the equilibrium structure, the conjugated chain at both ends or in the middle of the chain connected with heterocyclic, aryl ring compounds, cycloalkene compounds, etc. and the conjugated chain to form a large conjugated system, the molecule of the internal hydrogen can be a number of various types of substituents to replace the CY dyes are often used in the labeling of proteins, antibodies, as well as small molecules, the labeling of the proteins and antibodies, you can For protein-antibody labeling, the conjugation can be accomplished by a simple mixing reaction. In the following, we introduce the labeling methods for protein-antibody labeling, which have certain reference significance.
