Chemical biology of genomic DNA: minimizing PCR bias

Chem Commun (Camb). 2014 Oct 18;50(81):12047-9. doi: 10.1039/c4cc05107f.

Abstract

The exquisite selectivity of chemical reactions enables the study of rare DNA bases. However, chemical modification of the genome can affect downstream analysis. We report a PCR bias caused by such modification, and exemplify a solution with the synthesis and characterization of a cleavable aldehyde-reactive biotinylation probe.
