FLUORESCENCE RESONANCE ENERGY TRANSFER DYE NUCLEOTIDE TERMINATORS: A NEW SYNTHETIC APPROACH FOR HIGH-THROUGHOUT DNA SEQUENCING
摘要:
Fluorescence resonance energy transfer (FRET) based dye-nucleotide terminators (10-13) were designed, synthesized, and formulated with Thermo Sequenase(TM) II DNA polymerase into a robust kit for high throughput DNA sequencing. The key energy transfer (ET) rigid and linear linker (2), required for the syntheses of energy transfer cassettes (6-9) was synthesized via Heck coupling reaction on t-Boc-L-4-iodo-phenylalanine (1) with N-TFA-propargylamine.
Fluorescence resonance energy transfer terminators for DNA sequencing
摘要:
A four-colour set of fluorescence resonance energy transfer dideoxy nucleotide terminators (10-13), have been synthesised using a rigid and linear tri-functional molecule (2), synthesised via Heck coupling reaction of t-Boc-L-4-iodophenylalanine (1) with N-TFA-propargylamine. Evaluation of the terminators in DNA sequencing reactions, in combination with Thermo Sequenase(TM) II DNA polymerase, demonstrated them to be excellent reagents for high-throughput DNA sequencing.
