Rhesus and human amniotic fluid proteins are highly homologous. In the 1090 protein ortholog pairs shared between human and rhesus amniotic fluid, the abundance (log intensity) was highly correlated across species at rhesus equivalent gestational age windows (a). Hierarchical clustering of all samples and ortholog pairs revealed clear separation of samples by species and clustering of samples by rhesus equivalent gestational age within a species (b).
