Nucleotides conjugated with a chelating agent and labeled with a lanthanide, especially terbium, are readily detected by time-resolved fluorimetry during and following gel electrophoresis. The labeled nucleotide conjugates are very stable, highly fluorescent with a long radiative lifetime and remain fluorescent during dilution and during gel electrophoresis and since an enhancement solution is not required for detection, the labeled nucleotide conjugates can be detectd on-line, if desired.
核苷酸与螯合剂共轭并用镧系元素(尤其是铽元素)标记后,在凝胶电泳过程中和电泳后很容易通过时间分辨荧光测定法进行检测。标记的核苷酸共轭物非常稳定,荧光强度高,辐射寿命长,在稀释过程中和凝胶电泳过程中都能保持荧光,而且由于检测不需要增强溶液,如果需要,标记的核苷酸共轭物可以在线检测。
