Applications
DescriptionP-Xylene-bis-pyridinium bromide is a cationic charged quencher that is commonly used in membrane fusion or permeability assays.
UsesD.P.X. has been used as a mounting medium for mounting:rat brain sections for immunohistochemistry studiesmouse small intestine sections for morphometry studiesgastrointestinal tract sections of rats for immunohistochemistry
General DescriptionD.P.X is a mixture of distyrene (polystyrene), a plasticizer (tricresyl phosphate), and xylene. It facilitates the protection of stains and can dry quickly.
