Abstract

Specifically stained staphylococcal alpha toxin particles were detected on unstained and nonspecifically stained ghost membranes when rabbit erythrocytes were exposed to alpha toxin and stained with fluorescein isothiocyanate-labeled specific antitoxin. Fading of the nonspecific staining was observed and was attributed to the degradation of the membranes by alpha toxin.

摘要

当兔红细胞暴露于α毒素并用异硫氰酸荧光素标记的特异性抗毒素染色时,在未染色和非特异性染色的血影膜上检测到特异性染色的葡萄球菌α毒素颗粒。观察到非特异性染色褪色,这归因于α毒素对膜的降解。
