Permeability assay protocol
WebAssay Principle The PAMPA assay for permeability measurement is based on the diffusion of a compound of interest through an artificial membrane. The PAMPA artificial membrane has a lipid-oil-lipid tri-layer structure constructed in the pores of a porous filter. WebJan 2, 2015 · This chapter aims at giving an overview about current and future in vitro methods to assess blood-brain barrier (BBB) permeability, focusing on artificial membrane and cell culture models. Potential and possible artificial membrane and cell culture models to meet the requirements of drug discovery issues are discussed.
