Description

Description

  • Qtracker 625 label has Ex/Em 405-585nm/625nm
  • Cytoplasmic delivery is not mediated by specific enzyme; therefore, no cell-type specificity has been observed
  • Delivery is typically accomplished in less than 1 hour
  • Qdot nanocrystals delivered are compatible with serum-sensitive cells
  • Intense fluorescence is maintained in complex cellular environments and under various biological conditions including changes in intracellular pH, temperature, and metabolic activity
  • Observe labeled cells using extensive continuous illumination, without the photobleaching and degradation problems often associated with organic dyes
  • Distributed in vesicles in cytoplasm, and are inherited by daughter cells for at least six generations: Fluorescence from the Qtracker labels can be seen up to a week after delivery in some cell lines
  • Long-term cellular retention makes kits suitable for studying cell motility, migration, differentiation, morphology, and many other cellular function studies
  • Labels do not leak out of intact cells to be taken up by adjacent cells in population
  • Can be easily monitored on variety of platforms, including flow cytometry, fluorescence/confocal microscopy, fluorescence microplate readers, and high-content imaging systems
  • Cytotoxicity of the materials use in Qtracker Cell Labeling Kits has been tested in a variety of cell lines including CHO, HeLa, U-118, 3T3, HUVEC, and Jurkat cells: Labeling with Qtracker Cell Labeling Kits appears to exert minimal impact on cellular surface marker expression, cell proliferation, cellular enzyme activity, and cell motility
  • Post-labeling, researchers have demonstrated a wide variety of applications for Qtracker labeled cells, including cell co-culture and cell assembly into heterotypic assemblies, multilineage differentiation, trans-differentiation versus cell fusion, embryonic and mesenchymal stem cell tracking, and cell migration dynamics
