摘要: Abstract 1. A hemolysin found in whole fly homogenates and midgut of Stomoxys calcitrans (L.) is heat labile, has a slightly acidic pH optimum, non-dialyzable. 2. Hemolytic activity enhanced by dialysis but not removal Ca2+ alone. 3. The hemolytic curves obtained are sigmoidal, which suggests some cooperative acivity. 4. This activated addition trypsin to the homogenates.
