Topic Construction of functionalized nucleic acids bearing selected reactive functional groups for bioconjugation
Faculty FCHT / FPBT VŠCHT, PřF UK
Abstract

Polymerase synthesis of base-modified oligonucleotides and nucleic acids (DNA and RNA) from base-functionalized nucleoside triphosphates (NTPs) will be studied. The starting modified NTPs will be prepared by aqueous cross-coupling reactions. The base-modifications will focus on chemically reactive groups for bioconjugation (i.e. cross-linking with proteins). Further post-synthetic chemical modifications of the functionalized nucleic acids will be also studied. Potential applications will include bioanalysis, diagnostics and chemical biology.
