Carybdea alata

FIGURE 41.1 Effect of heat on venom hemolysis. Sheep RBCs are incubated in various concentrations of Carybdea alata venom (bars). Hemolysis is determined spectrophotometrically as the absorbance of supernatant at 414 nm (vertical axis). Hemolysis, expressed as the percentage change of absorbance relative to that observed when exposed to buffer alone, is significantly reduced by heating concentrated venom to 45°C.
