Lactosylation of albumin reduces uptake rate of dibromosulfophthalein in perfused rat liver and dissociation rate from albumin In Vitro
Peter Van Der Sluijs, Bart Postema, Dirk K. F. Meijer – 1 July 1987 – Two types of models have recently been proposed to describe hepatic uptake kinetics of protein bound drugs: a model in which dissociation from plasma protein is rate limiting the process, and a model in which an interaction between protein and hepatocyte surface is thought to promote dissociation and uptake of the drug. This study was designed to investigate several aspects of both models, using lactosylated albumin as a binding protein that can interact with the Ashwell receptor abundantly present on the hepatocyte.
