    CellBrite® Steady Membrane Staining Kits allow fluorescence imaging of cell surface for up to several days in culture. The CellBrite® Steady Dyes are unique fluorescent membrane probes that distribute between the cell surface and intracellular compartments, so cells retain cell surface staining over time. With the use of CellBrite® Steady Enhancer, intracellular staining can be reduced or eliminated for imaging of cell outlines or boundaries.

    • Retained on cell surface, unlike other membrane dyes that are rapidly internalized
    • Image live cell surface membranes for 24 hours or longer
    • Optional Enhancer masks intracellular signal for selective imaging of cell surface
    • Rapid, even staining in complete cell culture medium
    • Dye colors from blue to near-IR, with STORM-compatible options

    Unlike other membrane/cell surface stains that are rapidly lost from the cell surface by endocytosis after labeling, CellBrite® Steady Dyes equilibrate between intracellular compartments and the plasma membrane. Cells retain surface staining in addition to intracellular staining over the course of hours to days in culture. CellBrite® Steady Enhancer is an optional reagent included in the kits that can be used to mask intracellular fluorescence of CellBrite® Steady Dyes, for more selective visualization of cell boundaries.

    Kit Components

    Kit sizes are based on 200 uL labeling volume, actual number of labelings may vary based on culture chamber size/staining volume.

    • Trial size kit (100 labelings):
      • CellBrite® Steady Dye, 1000X in DMSO, 20 uL

    Selecting a CellBrite® Steady Dye

    CellBrite® Steady Dyes are available in colors from blue to near-infrared. CellBrite® Steady 550, 650, and 685 fluorophores are compatible with super-resolution imaging by STORM. Masking of intracellular fluorescence by CellBrite® Steady Enhancer tends to show more complete masking of intracellular fluorescence for far-red CellBrite® Steady 650 and CellBrite® Steady 685 dyes.

    Tips for Success

    Washing after staining is optional for imaging by confocal microscopy, but is required for imaging by epifluorescence. For dyes with fluorescence in the visible range (405, 488, and 550), staining may or may not be visible through the microscope eyepieces without washing, so you may need to use bright field or another marker to focus on cells initially for no-wash confocal imaging.

    CellBrite® Steady Dyes have low toxicity and can be continuously incubated in cell culture medium. Enhancer may be toxic to some cell types, especially at higher concentrations. Enhancer may be incubated together with membrane dyes or added after staining to minimize any potential effect of Enhancer on cells. See the Product Protocol for details.
