Abstract
The cytolytic action of cardiotoxin analogue III from the venom of the Formosan cobra on chick embryonal fibroblasts transformed with a temperature-sensitive mutant of Rous sarcoma virus was investigated. The 50% effective dose of the toxin for the cells cultured at a non-permissive temperature (41 degrees C) or for noninfected normal cells was about 8 micrograms/ml whereas the value was 2 micrograms/ml for the cells cultured at a permissive temperature (36 degrees C). This indicates that the transformed cells became more susceptible to the cytolytic action of the toxin than the non-transformed cells.
