ITIH4 and infection: Analyses of gp120 derived from virus prepared by infection of peripheral blood mononuclear cells (PBMCs) with viruses from clade A (92RW009), clade B (JRCSF), and clade C (93IN905) showed a predominantly oligomannose glycan composition (62–79% Man5–9GlcNAc2, Figure 1F, G, H) with a distribution similar to that previously reported for PBMC-derived gp120JRCSF[11].
