Here we present a sensitive and specific assay for thrombin through the affinity capture of thrombin with mRNA display generated peptide aptamers on magnetic beads and the subsequent thrombin-involved enzymatic reaction. Thrombin at 50 fM can be detected.
在这里,我们提出了一种灵敏而特异的凝血酶检测方法,通过磁珠上的 mRNA 显示生成的多肽适配体亲和性捕获凝血酶,随后进行凝血酶参与的酶促反应。可以检测到 50 fM 的凝血酶。
