    • The invention is based on the discovery of the epitope in the Stx1 protein for the 13C4 antibody. The invention features non-full length Stx1 polypeptides that include the epitope for the 13C4 monoclonal antibody epitope. The invention also features methods of producing anti-Stx1 antibodies specific for the 13C4 epitope of the Stx1 protein. Additionally, the invention features methods for treating a subject having, or at risk of developing, a Shiga toxin associated disease (e.g., hemolytic uremia syndrome and diseases associated with E. coli and S. dysenteriae infection) with a polypeptide that includes the 13C4 epitope or with an anti-Stx1 antibody developed using the methods of the invention. Furthermore, the invention features the detection of Stx1 in a sample using the antibodies developed using the methods of the invention.
    • 本发明基于用于13C4抗体的Stx1蛋白中的表位的发现。 本发明的特征是非全长Stx1多肽,其包括13C4单克隆抗体表位的表位。 本发明还具有产生对Stx1蛋白的13C4表位特异的抗Stx1抗体的方法。 另外,本发明的特征在于具有包含13C4表位的多肽或具有发展志贺毒素相关疾病(例如,溶血性尿毒症综合征和与大肠杆菌和痢疾杆菌感染相关的疾病)的受试者的方法。 或使用本发明的方法开发的抗Stx1抗体。 此外,本发明的特征在于使用使用本发明的方法开发的抗体检测样品中的Stx1。
