Table 3. Results of N-glycan analysis of hCG and summary of the effects of overexpression of GnTIV, GnTV and knockdown of GalT4 on the glycosylation of the substrate hCG.

A1, mono-antennary structure; A2, bi-antennary structure; A3, tri-antennary structure; A4, tetra-antennary structure. G1, G2, G3, mono-, bi-, tri-galactosylated structures. Results are presented as the relative percentages of each type of glycan structure.
