  SITE-SPECIFIC LABELING OF AFFINITY TAGS IN FUSION PROTEINS

  摘要：

  本发明提供了一种方法和荧光化合物，通过选择性地与亲和标签结合，从而促进融合蛋白的检测和标记。所述荧光化合物具有通式A(B)n，其中A是荧光团，B是带电化学基团、蛋白质或其片段的绑定域，n是1-6的整数，但该蛋白质或其片段不是抗体或由抗体产生的。本发明还提供了特定的荧光化合物和方法，用于检测和标记含有聚组氨酸亲和标签的融合蛋白。这些化合物具有通式A(L)m(B)n，其中A是荧光团，L是连接器，B是醋酸绑定域，m是1到4的整数，n是1到6的整数。醋酸基团直接与亲和标签中的正电荷组氨酸残基相互作用，有效地标记和检测含有此类亲和标签的融合蛋白，当其存在于酸性或中性环境中时。

  The present invention provides methods and fluorescent compounds that facilitate detecting and labeling of a fusion protein by being capable of selectively binding to an affinity tag. The fluorescent compounds have the general formula A(B)n, wherein A is a fluorophore, B is a binding domain that is a charged chemical moiety, a protein or fragment thereof and n is an integer from 1-6 with the proviso that the protein or fragment thereof not be an antibody or generated from an antibody. The present invention provides specific fluorescent compounds and methods used to detect and label fusion proteins that contain a poly-histidine affinity tag. These compounds have the general formula A(L)m(B)n wherein A is a fluorophore, L is a linker, B is an acetic acid binding domain, m is an integer from 1 to 4 and n is an integer from 1 to 6. The acetic acid groups interact directly with the positively charged histidine residues of the affinity tag to effectively label and detect a fusion protein containing such an affinity tag when present in an acidic or neutral environment.
