What is Fluorescent Molecule-Oligonucleotide Conjugation?

The conjugation of fluorescent molecules and oligonucleotides allows the visualisation and detection of oligonucleotides by fluorescence microscopy or other fluorescence-based techniques widely applied in basic biological and biomedical research.

• Synthesis Steps for Fluorescent Molecule-Oligonucleotide Conjugation

The process of conjugation usually consists of two main steps, including the labelling of the oligonucleotide with the reactive group and the attachment of the fluorescent molecule to the reactive group.

• Firstly, the oligonucleotide is modified to introduce the reactive group, which can be achieved by adding the modified nucleotide during oligonucleotide synthesis or by post-synthetic modification. Common reactive groups for conjugation include amino groups (-NH2), thiol groups (-SH) or carboxyl groups (-COOH).
• Subsequently, attachment of the fluorescent molecule to the reactive group on the oligonucleotide is achieved by various chemical reactions, such as amidation, thiolation or click chemistry.
