Supplemental Figure S3.
Proportion of Spliced HLA-presented peptides in HLA-class-I and -II. The fraction of HLA-class-I spliced peptides detected (3.1%) is much smaller than that previously detected by Liepe et al. (Science 2016) (30% of HLA-class-I immunopeptidome). Both HLA-class-I and -II spliced peptides are identified, but to different extents.
