Cell Surface & Membrane Dyes

Biotium offers two new classes of dyes for covalent labeling of the cell surface that are unique in that they can withstand fixation and permeabilization for subsequent IF staining. CellBrite™ Fix dyes are fluorogenic membrane dyes that covalently stain the plasma membrane in live cells. MemBrite™ Fix dyes covalently label cell surface proteins, and are available in with a wide selection of bright and photostable colors.

We also offer classic membrane and membrane potential dyes, including CellBrite™ and CellBrite™ NIR dyes, which are lipophilic carbocyanine dyes that stain the plasma membrane of cells and are non-toxic for long-term tracking.
