| Description | P-Xylene-bis-pyridinium bromide is a cationic charged quencher that is commonly used in membrane fusion or permeability assays. | | Uses | D.P.X. has been used as a mounting medium for mounting:
- rat brain sections for immunohistochemistry studies
- mouse small intestine sections for morphometry studies
- gastrointestinal tract sections of rats for immunohistochemistry
| | General Description | D.P.X is a mixture of distyrene (polystyrene), a plasticizer (tricresyl phosphate), and xylene. It facilitates the protection of stains and can dry quickly. | | Biological Activity | Cationic fluorescence quencher used with ANTS to study membrane permeability and liposome lysis. | | IC 50 | hAChE: 1540 μM (IC50); BChE: 529 μM (IC50) | | Excitation / Emission Maximum | 541 nm/567 nm |
