hemolysin

 [he-mol´ĭ-sin]
a substance that liberates hemoglobin from erythrocytes by interrupting their structural integrity.

he·mol·y·sin

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

hemolysin

(hĭ-mŏl′ĭ-sĭn, hē′mə-lī′-)
n.
An agent or substance, such as an antibody or a bacterial toxin, that causes the destruction of red blood cells, thereby liberating hemoglobin.

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.
