Isolation and characterization of the cardiotonic polypeptide anthopleurin-A from the sea anemone Anthopleura xanthogrammica.
A highly potent cardiotonic polypeptide, anthopleurin-A, was isolated from the sea anemone, Anthopleura xanthogrammica (Brandt), using solvent partition, gel permeation chromatography, and cation-exchange chromatography. It is a pure basic polypeptide wtih a molecular weight of about 5500.
