Biotium offers a variety of cell surface stains that depend on the workflow and application.
CytoLiner™ Fixed Cell Membrane Stains are novel lipophilic fluorescent dyes designed for selective and robust labeling of the plasma membrane in formaldehyde-fixed cells.
CellBrite® Fix and
MemBrite® Fix Membrane Staining Kits offer stable covalent labeling of cell surfaces and can withstand fixation and permeabilization. These stains are designed to be used on live cells that will be fixed shortly after.
CellBrite® Steady Membrane Staining Kits were designed specifically for staining cell surfaces in live cells for long-term imaging. The stains are retained on the cell surface, unlike other membrane dyes that are rapidly internalized.
, which are lipophilic carbocyanine dyes that stain the plasma membrane of cells and are non-toxic for long-term tracking.
