Abstract

A simple immunochromatographic assay, Capilia TB, using anti-MPB64 monoclonal antibodies, is a kit for discriminating between the Mycobacterium tuberculosis complex and mycobacteria other than tubercle bacilli. The sensitivity of the kit was estimated to be 99.2% (381 of 384 samples). The sequencing analysis revealed that all of the Capilia TB-negative isolates had mutations within the mpb64 gene, leading to the production of an incomplete protein as a result of a deletion of the C-terminal region of the protein.

摘要

一种简单的免疫层析检测方法Capilia TB,使用抗MPB64单克隆抗体,是一种用于区分结核分枝杆菌复合群和非结核分枝杆菌的试剂盒。该试剂盒的灵敏度估计为99.2%(384个样本中的381个)。测序分析表明,所有Capilia TB阴性分离株的mpb64基因均发生突变,导致该蛋白C末端区域缺失,从而产生不完全蛋白。
