Figure 5: Comparison of glycan abundance by structure type. These comparisons were made because previous FSH glycan structure determinations were summarized using this type of grouping. In each case pituitary hFSH glycan relative abundance is compared with the other FSH preparations in this study as well as two published hFSH glycan studies. A. Comparison of pituitary hFSH AFP-7298 with pituitary hFSH [17] and pituitary hFSH [18,19]. B. Comparison of pituitary and urinary hFSH glycans by structure type. C. Comparison of pituitary hFSH glycans with those from recombinant GH3-hFSH. D. Comparison of pituitary hFSH and hFSH24 glycans. E. Comparison of pituitary hFSH and hFSH21 glycans. F. Comparison of pituitary hFSH and hFSH21/18 glycans.
