Proteome analysis of intestinal chitinous barrier membrane of the tunicate Ciona intestinalis Type A

Proteome analysis of the surface matrix of chitinous barrier membranes of the tunicate Ciona intestinalis Type A, a marine filter-feeding invertebrate chordate. This chitinous membrane separate food microbes from the gut epithelium, as a physical barrier. As controls, we used mucus cords from the esophagus.
