LEC14, a dominant Chinese hamster ovary glycosylation mutant expresses complex N-glycans with a new N-acetylglucosamine residue in the core region.

The Journal of biological chemistry - 29 Mar 1996

Raju T S, Stanley P

Abstract excerpt

The Chinese hamster ovary cell (CHO) glycosylation mutant, LEC14, was previously selected for resistance to pea lectin (Pisum sativum agglutinin) and shown to behave dominantly. The lectin resistance properties of LEC14 cells are related to, but distinct from, those of LEC18, a dominant Chinese hamster ovary mutant that synthesizes complex N-glycans with a novel O-6-linked GlcNAc residue in the core region (Raju,...
