he·mol·y·sin

(hē-mol'i-sin)
1. Any substance elaborated by a living agent and capable of lysing red blood cells and liberating their hemoglobin.
Synonym(s): erythrocytolysin, erythrolysin, haemolysin.
2. A sensitizing (complement-fixing) antibody that combines with red blood cells of the antigenic type that stimulated formation of the hemolysin, so that complement fixes with the antibody-cell union and causes dissolution of the cells.

haemolysin

a property of blood serum which can destroy red blood cells.
