Faster in vivo clearance of human embryonic kidney than Chinese hamster ovary cell derived protein: Role of glycan mediated clearance

J Biosci Bioeng. 2015 Jun;119(6):657-60. doi: 10.1016/j.jbiosc.2014.11.008. Epub 2015 Jan 6.

Abstract

This investigation used in vivo and in vitro tools to study pharmacokinetics and glycosylation of two monomeric antibodies produced either transiently by HEK293 cells or stably by Chinese hamster ovary cells, and demonstrated that higher in vivo clearance of human embryonic kidney antibody was due to higher glycosylation, thus higher mannose receptor mediated uptake.

Keywords: Antibody; Clearance; Glycosylation; Mannan; Mannose receptor; Pharmacokinetics.
