Abstract

1. 1. Hemolysins of the sea nettle, Chrysaora quinquecirrha, and the lions' mane jellyfish, Cyanea capillata, collected in the Delaware Bay were partially purified by sequential gel-filtration and high performance liquid chromatography. 2. 2. The nematocyst contents of both jellyfish had hemolytically active fractions containing large quantities of glycine and serine along with an unknown amino acid residue. 3. 3. The Chrysaora hemolysin appeared to have a mol. wt greater than 6000 but less than 10,000 daltons. 4. 4. Glycophorins were the most effective inhibitors to the hemolysins at the lowest concentration. © 1989.
