Ralph Russ Canine Kidney assay

RRCK assay

definition

The RRCK permeability assay is a proprietary in vitro assay that uses a specific subclone of the MDCK canine kidney cell line to determine a compound's passive membrane permeability coefficient (Papp) across a cellular monolayer. The RRCK cell line is characterized by low or minimal expression of endogenous efflux transporters, which reduces interference from active transport mechanisms, thus isolating the passive diffusion component of drug permeation.
