Mechanically linked energy transfer labels comprising at least one donor fluorophore, at least one acceptor fluorophore, and at least one support member, wherein steric interactions between the donor fluorophore(s), the acceptor fluorophore(s), and/or the support member(s) induce non-covalent association between the fluorophores and the support member(s), thereby forming a three-dimensional macromolecular structure which mechanically links the donor fluorophore(s) and the acceptor fluorophore(s). Fluorescence resonance energy transfer (FRET) occurs from donor fluorophore to acceptor fluorophore through space. No direct connectivity with covalent bonds exists between the fluorophores. Instead, mechanical barriers hold the donor/acceptor fluorophores in place during the FRET process.
机械连接能量转移标签包括至少一个给体荧光物,至少一个受体荧光物和至少一个支撑成员,其中给体荧光物、受体荧光物和/或支撑成员之间的立体作用引起荧光物和支撑成员之间的非共价结合,从而形成一个三维大分子结构,机械地连接给体荧光物和受体荧光物。荧光共振能量转移(FRET)通过空间从给体荧光物到受体荧光物发生。荧光物之间不存在共价键的直接连接。相反,在FRET过程中,机械障碍使给体/受体荧光物保持在原位。
