抗毒素抗毒素antitoxin细菌毒素（通常指外毒素)的对应抗体或含有这种抗体的免疫血清。它能中和相对应的外毒素的毒性作用。机体经产生外毒素而致病的病原菌，如白喉、破伤风、气性坏疽等菌感染，即能产生抗毒素。外毒素经甲醛处理后，可丧失毒性而保持抗原性，成为类毒素。在医疗实践中，应用类毒素进行免疫预防接种，使机体产生相应的抗毒素，可以预防疾病。在免疫治疗中，常用细菌的外毒素、类毒素或其他毒物（如蛇毒等）对马进行免疫注射，使马产生抗毒素，然后取其血清，经浓缩提纯制成抗毒素，这不仅可以提高效价，而且可以减轻副作用。这种动物来源的抗毒素血清，对人体具有两重性：一方面对病人提供了特异性抗毒素抗体，可中和体内相应的外毒素，起到防治的作用；另一方面是具有抗原性的异种蛋白，能刺激人体产生抗马血清蛋白的抗体，以后再次接受马的免疫血清时，可能发生超敏反应。已用胃蛋白水解酶水解提纯的IgG分子，保留具有抗体活性的F（ab)2段，尽可能除去特异性抗原决定簇，既能大大提高效价，也可以减少发生超敏反应的机会。
