Figure 1From: A proteomic approach for studying insect phylogeny: CAPA peptides of ancient insect taxa (Dictyoptera, Blattoptera) as a test caseComparison of MALDI-TOF mass spectra (mass range 1000–2000 Da) of single abdominal PSO preparations of Blaberus craniifer and Bantua robusta (= peptide hormone fingerprint). Only few abundant substances are detectable. Underlying sequences were used for phylogenetic analyses.Back to article page
