N2  - Liposomes have been used since the 1970's to encapsulate drugs envisaging enhancement in efficacy and therapeutic index, avoidance of side effects and increase in the encapsulated agent stability. The major problem when encapsulating snake venoms is the liposomal membrane instability caused by venom phospholipases. Here the results obtained encapsulating Crotalus durissimus terrificus and a pool of Bothropic venoms within liposomes (LC and LB, respectively) used to produce anti-venom sera are presented. The strategy was to modify the immunization protocol to enhance antibody production and to minimize toxic effects by encapsulating inactivated venoms within stabilized liposomes. Chemically modified venoms were solubilised in a buffer containing an inhibitor and a chelating agent. The structures of the venoms were analysed by UV, CD spectroscopy and ELISA. In spite of the differences in the helical content between natural and modified venoms, they were recognized by horse anti-sera. To maintain long-term stabi.<p />  <p>Language: en</p>
