From: Partial HIV C2V3 envelope sequence analysis reveals association of coreceptor tropism, envelope glycosylation and viral genotypic variability among Kenyan patients on HAART

Fig. 1

Proportion of isolates with PNGs at specific amino acid position relative to HXB2 reference sequence. Data is shown for isolates derived from cellular blood compartment (a), and those derived from cell-free blood (plasma) (b). Each vertical spike represents the proportion of sequences glycosylated at that specific sequence position. The cell-associated virus isolates are proportionally more glycosylated (more longer vertical spikes) than cell-free isolates. Red spikes show amino acid position (N399 and N408) at which glycosylation differed significantly between extracellular and cell-derived isolates
