Abstract
1. Nematocyst structural proteins (NSP) from the sea anemones Aiptasia pallida and Metridium senile and the siphonophore Physalia physalis a re primarily low molecular weight collagens linked by disulfide bonds. 2. NSP patterns resolved by SDS-PAGE revealed a common, major collage n species (40 kDa) in each nematocyst type, together with other collag ens and non-thiol-containing proteins. 3. For each cnidarian, NSP glyc osylation profiles were significantly different. 4. Monoclonal antibod ies against Aiptasia NSP demonstrated a differential distribution betw een capsule wall and thread. 5. NSP differences would account for the diversity of morphologic and functional types.
