Active Nematocyst Isolation Via Nudibranchs
Marine Biotechnology, 2009Cnidarian venoms are potentially valuable tools for biomedical research and drug development. They are contained within nematocysts, the stinging organelles of cnidarians. Several methods exist for the isolation of nematocysts from cnidarian tissues; most are tedious and target nematocysts from specific tissues.

Coelenterate nematocysts bind immunoglobulins
Experientia, 1982Nematocyst capsules ofActinia equina were shown to bind immunoglobulins. Binding is not affected by EDTA-pretreatment or incubation with N-acetyl-galactosamine and N-acetyl-glucosamine.

The Cell Biology of Nematocysts
1994Publisher Summary This chapter focuses on the cell biology of nematocysts. Nematocysts, the most widely used term to describe the “stinging capsules” characteristic of the phylum Cnidaria, constitute the best-studied and most diverse group of cnidae, the secretory products of cnidocytes.

Biodeterioration of polyethylene by jellyfish nematocyst protein
Marine Pollution Bulletin, 2023Plastic pollution is one of the major global problems existing now-a-days and has become a cause of serious concern in coastal and marine ecosystems. Increased accumulation of plastics in the aquatic environment by anthropogenic sources results the alteration of the aquatic ecosystem and its functioning.

Cytochemical Research on Coelenterate Nematocysts
Nature, 1955A NOTE by T. M. Yanagita and T. Wada1 suggesting, after C. H. Brown2, the possible keratin nature of coelenterate nematocysts has directed my attention to the subject. In 1952 I had observed the pronounced metachromatic colour produced by dilute thionin on large nematocysts from a siphonophore, Halistemma sp.

Beachside preparation of jellyfish nematocyst tentacles
Toxicon, 1992A comparison of methods for preparing a jellyfish nematocyst suspension from sea nettle (Chrysaora quinquecirrha) fishing tentacles at the beachside was conducted. Autolysis of the tentacle followed by straining and sedimentation on ice was found to be a satisfactory technique.

Zootaxa, 2006
Nematocysts (stinging organelles) are an important part of cnidarian identification, but the cnidomes of many species remain poorly known because of identification difficulties and confusing nomenclature. Currently, the cnidomes of 20 cubozoan species are documented in whole or in part (including four undescribed species and five newly described ...

Tissue and Cell, 1984
Some nudibranchs that feed on cnidarians are known to store nematocysts within cnidophage cells and use them for their own defense. Most of the nematocysts are in direct contact with the cytoplasm of the cnidophage. Nematocysts are not subjected to lysosomal enzymes because any phagocytic membrane that surrounded the nematocyst after engulfment does ...

Cobalt Staining OfActinia EquinaNematocysts
Stain Technology, 1978Nematocysts of Actinia equina are stained black by incubation in 2% CoCl2 followed by an aqueous wash and H2S treatment. They are also stained positively by morin. Nematocysts isolated from the acrorhage were found to have a high concentration of calcium of which only 30% was "free." It is suggested that the high concentration of calcium in the ...
