Invitrogen™ Qtracker™ 655 Cell Labeling Kit (Trial Size)

Invitrogen™ Qtracker™ 655 Cell Labeling Kit (Trial Size)

The Qtracker™ 655 Cell Labeling Kit uses a custom targeting peptide to deliver far red-fluorescent Qdot™ 655 probe (ex/em 405–615/655 nm) into the cytoplasm of live cells. Once inside the cells, the Qdot™ 655 probe provides an intense, stable fluorescence that can be traced through several generations and is not transferred to adjacent cells in a population. This trial-size version offers a convenient introduction to the Qtracker™ cell labeling technology at an affordable price.

Features

• Qtracker™ probes allow for continuous illumination, without photobleaching or degradation problems often associated with organic dyes
• Simple to use—add Qtracker™ labeling solution to cells in serum-containing media, incubate one hour, then detect and track the cells
• Provide an intense, stable fluorescence that can be traced through several generations
• Excellent tool for long-term tracking or imaging studies of live cells, including migration, motility, morphology, and other cell function assays
