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.
CellBrite™ Fix Membrane Stains

Wheat Germ Agglutinin (WGA) Conjugates
A wheat germ agglutinin (WGA) lectin labeled with Biotium’s CF® Dyes or HRP. It is a carbohydrate-binding lectin that has high affinity for sialic acid and N-acetylglucosamine and stains yeast bud scars as well as the cell membrane of gram+ bacteria and mammalian cells.

1,6-Diphenyl-1,3,5-hexatriene
1,6-Diphenyl-1,3,5-hexatriene (DPH) is almost non-fluorescent in water, but it exhibits a strong increase in fluorescence after intercalation into membranes and can be used as a probe for viscosity, polarity and lipid order.
