Papp permeability

WebMethod Description. The Caco-2 permeability assay measures the permeability of compounds through a human intestinal epithelial cell barrier. Therefore, the endpoint measured is intestinal permeability (expressed as apparent permeability - Papp value). The test method appears more relevant for drug permeability studies. WebMar 2, 2024 · The reference compounds used in these tests are categorized as high permeability, low permeability and P-gp substrate. In the case of CacoReady, the main reference high permeability compound is metoprolol (Papp A-B >10 cm/s) and for the low, atenolol (Papp A-B <0.5 cm/s). Digoxin is used as P-gp substrate with a Papp A-B <1 cm/s.
