What is fluorescent labeling ？

The compounds on which fluorescent labeling depends are called fluorescent substances . Fluorescent substances refer to compounds with the chemical structure of conjugated double bond system , When exposed to ultraviolet or blue violet light , Can be excited into an excited state , When the ground state is restored from the excited state , Emit fluorescence . Fluorescent labeling technology refers to the covalent binding or physical adsorption of fluorescent substances on a group of the molecule to be studied , Using its fluorescence characteristics to provide the information of the studied object . Fluorescent labeled non radioactive contamination , It is easy to operate , Fluorescent markers have been widely used in many research fields .

Peptide nucleic acid , A class of peptides that replace the sugar phosphate backbone DNA Analogues , He is a Danish organic chemist Ole Buchardt And biochemists Peter Nielsen On 20 century 80 A new nucleic acid sequence specific reagent that began to be studied in the s . It was in the first generation 、 Based on the second generation of antisense reagents , The third generation of antisense reagents designed, constructed and finally synthesized by computer , It's a brand new DNA Analogues , That is, neutral peptide amide 2- Amino ethyl glycine bond replaces DNA Pentose phosphate diester bond skeleton in , The rest are related to DNA identical ,PNA Can pass Watson-Crick The form of base pairing is recognized and combined DNA or RNA Sequence , Form a stable double helix structure .
