Abstract

Characterization and Pharmacological Activities of Jellyfish, Chrysaora hysoscella Captured in Bushehr Port, Iran

Highlights

  • Fishing over the past half century has resulted in an increase in previously suppressed gelatinous zooplanktons feeding on marine food which is not much consumed by the fish anymore [1, 2]

  • The electrophoretic profile, with 12.5% acrylamide gel of jellyfish venom showed at least 3 different major protein components with a range

  • Caseinase activity of the venom was assayed by colorimetric experiments

Summary

Introduction

Fishing over the past half century has resulted in an increase in previously suppressed gelatinous zooplanktons (jellyfish) feeding on marine food which is not much consumed by the fish anymore [1, 2]. Crambionella orsini has become abundant in warm waters including the coasts of southern provinces of Iran boundary to Persian Gulf [4]. The presence of these creatures has become dangerous for swimmers and fishermen causing local and systemic reactions including redness, pain, rash, itching and other cutaneous manifestations especially in warm months of the year. The aim of this study was extracting the jellyfish nematocyst to study venom protein components and caseinase content by SDS-PAGE analysis and RP-HPLC. Results: After separation of tentacles and isolation of their nematocysts, three different major protein components were revealed at 72-250 kDa with SDS-PAGE, signifying the presence of peptides in its venom.
