2 Figure S1 Figure S1: Protein intensity data of vestibular schwannoma perilymph samples depicted in a multi-scatter-plot by Pearson Compared was the protein distribution analyzed by label free quantification (LFQ) within the vestibular schwannoma group (n = 4) for measurement of the linear correlation between two variables. Each point shows the quantitative value of a detected protein by mass spectrometry in two samples of the vestibular schwannoma group. This diagram shows only a slight heterogeneity of the samples.
