Microheterogeneity of a purified IgG1 due to asymmetric Fab glycosylation.


A murine monoclonal anti-granulocyte IgG1, IMMU-MN3, was seen to exhibit heterogeneity. On reduced SDS-PAGE, the purified antibody appeared as two heavy-chain bands of unequal intensity, and only one light-chain band. Hydrophobic interaction chromatography (HIC) also resolved two populations of the IMMU-MN3 antibody. Based on Concanavalin A affinity… (More)
