Characteristics of human primary immune cell-based spectral library generated by Spectronaut. The number of proteins in individual primary immune cell libraries and the combined library is compared in a bar graph (a). The Venn diagram of individual primary immune cell libraries represents the characteristics of each library (b). Venn diagram showing the number of proteins in the three spectral libraries: ours, public pan-human library, and public t-cell library (c). Venn diagram showing the number of peptides in three spectral libraries: ours, the public pan-human library, and the public T cell library (d).
