An improved procedure based on centrifugation at 37,000 g has been developed for isolating the antineoplastic glycoprotein strongylostatin 1 from Strongylocentrotus droebachiensis (Müller). The green sea urchin has also been found to contain a second protein anticancer constituent designated strongylostatin 2. Treatment of the murine P3S8 lymphocytic leukemia with strongylostatin 2 resulted in 39-42% life extension at a dose of 4.5 mg/kg.
