Most recent studies of vanadium in ascidian blood indicate the signet ring cell as the cell type that stores vanadium. However, in Phallusia fumigata the situation is less clear, with contradictory reports. Therefore, the blood cells of the ascidian

Some ascidians (sea squirts) accumulate the transitional metal vanadium in their blood cells at concentrations of up to 350 mM, about 10(7) times its concentration found in seawater. There are approximately 10 different types of blood cell in ascidia

The "Henze solution", derived originally from the aqueous extraction of pelleted whole blood from the ascidian Phallusia mammillata, was examined using spectral studies. The aqueous extraction of fractionated blood cells including compartment cells,

A study was made on the effect of vanadium, in both the tetravalent state in vanadyl sulphate and in the pentavalent state in sodium meta-vanadate, and ortho-vanadate, on the proteolysis of azocasein by two serine proteases, trypsin and subtilisin an

Summary A polyclonal antibody raised against the hatching enzyme of Ciona intestinalis (D'Aniello et al., 1997) was used on larvae of different ages in whole mount immunofluorescence experiments in order to localize the cells secreting the enzyme. Af

A novel polypeptide containing the unusual posttranslationally modified amino acids l -3,4,5-trihydroxyphenylalanine (TOPA) and l -6-bromotryptophan (6-BrW) has been isolated from the morula cells of the vanadium-accumulating ascidian, Phallusia mamm

Proteolytic activity on azocasein was studied in the hemocytes of vanadium-accumulating ascidians (Phallusia mammillata and Ciona intestinalis) and iron-accumulating ascidians (Halocynthia papillosa and Microcosmus sulcatus). A possible inhibitory ro
