Conjugation and labelingCyanine
Cyanine dyes are a type of fluorescent dye based on cyanine structure, with excellent near-infrared optical properties and adjustable spectral characteristics. Their unique molecular structure makes them widely used in biological imaging, in vivo detection and molecular probes. Due to the characteristics of low scattering and high tissue penetration in the near-infrared region, cyanine dyes are particularly suitable for deep tissue imaging and in vivo tracing studies.
