Unlike traditional lipophilic membrane dyes like DiO and DiI, CellBrite™ Fix dyes are fluorogenic lipophilic dyes that covalently bind the surface of live cells. The staining is simple, rapid, and much more uniform than other membrane dyes. Most importantly, surface staining is retained after fixation and permeabilization for immunofluorescence or other co-staining.

-       Only membrane dyes that withstand permeabilization after fixation

-       Simple protocol

-       Bright, uniform staining in 10-15 minutes

-       Available with green, red, or far-red fluorescence
