Fluorescent dyes have been used for many years to label cells for microscopy studies, and a variety of dyes in the visible fluorescence spectrum are available to label different cellular compartments and organelles. Efficient delivery of the fluorophore to the cell without excessively modifying surface proteins or perturbing cell function is the major biotechnological challenge. In addition, researchers have taken on the challenge of in vivo imaging, focusing on near infrared (NIR) dyes that fluoresce in a spectral region better suited for in vivo imaging due to reduced background and higher tissue penetration. Here we introduce VivoTrack™ 680, a novel NIR dye that has a long aliphatic tail to facilitate intercalation into the lipid bilayer of the cell. This agent can label a variety of cells brightly and uniformly without requiring harsh organics such as DMSO or ethanol, chemicals known to affect cell function. The labeled cells retain excellent viability and normal proliferative capacity, and significant signal is retained in dividing cells in vitro for more than 7 days. Many different cell types can be labeled for in vivo transfer or implantation, and in vivo utility is illustrated,by non-invasively tracking fluorescent primary macrophages to sites of inflammation by NIR fluorescent imaging.
VivoTrack 680 (Explorer Kit) is a near infrared fluorescent cell labeling agent that intercalates into the plasma membrane of primary cells and cell lines. Cells are brightly labeled and retain excellent viability and function, with the near infrared wavelength of the fluorescence offering optimal in vitro and in vivo detection.
