Abstract:
The new molecular ligand naphthyridine carbamate dimer (NC), possessing 2-amino-1,8-naphthyridines and a carbamate linker, specially binds to guanine-guanine (G-G) mismatch in duplex DNA. The results of T(m) measurements showed that NC selectively bound to CGG/CGG triad with high deltaT(m) of 23.1 degrees C. The exclusive stoichiometry 2:1 of the complex of NC with CGG/CGG triad, obtained by the measurements of cold spray ionization time-of-flight mass spectrometry (CSI-TOF MS), showed that NC bound to CGG/CGG triad strongly with two molecules.

Labeling DNA Probes
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Maxam-Gilbert Sequencing
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
