Caco-2 Permeability

Rugged and Validated Predefined and Custom Designed Assays

We are focused on translating cellular science into human outcomes. Our Caco-2 permeability test system is uniquely validated for both P-gp interaction and BCS permeability classification studies, potentially enabling you to waive clinical P-gp and/or human BA/BE studies. The same validated Caco-2 test system used for definitive P-gp and BCS studies is used for permeability screening studies such as this.

We are comfortable saying, "nobody knows the Caco-2 permeability model better than Absorption Systems."

The human intestinal Caco-2 cell line has been used extensively as a model of the intestinal barrier. Originally obtained from a human colon adenocarcinoma, the cells undergo a process of spontaneous differentiation in culture, leading to the formation of a monolayer expressing a phenotype characteristic of mature enterocytes. Our co-founder and Chief Scientific Officer, Ismael Hidalgo, pioneered the use of Caco-2 cell monolayers to predict intestinal drug absorption twenty years ago. His seminal paper on the topic (Hidalgo et al. Gastroenterology 1989; 96:736-749) has been cited more than 1000 times.
