Here we proposed α-l-arabinofuranosidase from Clostridium thermocellum as an enzyme for signal amplification in bioanalysis whose activity does not exist in human cells. Combination of this enzyme and β-galactosidase enabled simultaneous detection of two different antigens on live cells.

α-l-阿拉伯呋喃糖苷酶作为人类细胞的正交酶

在这里，我们提出了来自热纤梭菌的α- l-阿拉伯呋喃糖苷酶作为生物分析中信号放大的酶，其活性在人类细胞中不存在。这种酶和 β-半乳糖苷酶的组合能够同时检测活细胞上的两种不同抗原。
