Time-resolved fluorimetric detection of lanthanide labeled nucleotides.

摘要

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.
