Abstract

Samples from concentrated aqueous solutions of β-lactam antibiotics were examined by gel filtration. The eluates were monitored by ultraviolet (uv) absorption and by passive cutaneous anaphylaxis (PCA) in guinea-pigs sensitized with appropriate antiserum raised in rabbits. The appearance of uv absorbing material, giving a positive PCA reaction, in fractions from the high molecular weight regions of the eluates from gel filtration of aged solutions was taken as evidence of antigenic polymer formation.

摘要

采用凝胶过滤法对β-内酰胺类抗生素浓水溶液的样本进行检测。用在兔体内产生的相应抗血清致敏豚鼠,通过紫外线(uv)吸收和被动皮肤过敏反应(PCA)对洗脱液进行监测。在老化溶液凝胶过滤洗脱液的高分子量区域的组分中,出现具有阳性PCA反应的紫外线吸收物质,被视为抗原性聚合物形成的证据。
