From: Spider genomes provide insight into composition and evolution of venom and silk

Venn diagrams with number of identified proteins based on 194 LC-MS/MS analyses (Supplementary Table 3). The silk analyses are based on in-solution trypsin digestion, while the body analyses are based on in-gel trypsin digestion. The venom analyses are based on a combination of the two methods. (a) Velvet spider. (b) Tarantula.
