Triazine-Modified 7-Deaza-2′-deoxyadenosines: Better Suited for Bioorthogonal Labeling of DNA by PCR than 2′-Deoxyuridines

22 May 2019

Researchers from the Karlsruhe Institute of Technology attached the bioorthogonally reactive 6-Ethynyl-1,2,4-triazine grou to the 7-position of 7-deaza-2-deoxyadenosine triphosphate and to the 5-position of 2-deoxyuridine triphosphate for subsequent labelling. Both, Primer extension experiments (PEX) and PCR amplification, show that 6-ethynyl-1,2,4-triazine is much better tolerated by the DNA polymerase when attached to the 7-position of 7-deaza-2-deoxyadenosine in comparison to the attachment at the 5-position of 2-deoxyuridine. Real-time kinetic observation of DNA polymerase activity during primer extension using switchSENSE® clearly shows this behavior and imply that bioorthogonal labeling strategies are better suited for 7-deaza-2-adenosines than conventional and available 2-deoxyuridines.

Specific inhibition of splicing factor activity by decoy RNA oligonucleotides

08 April 2019

In their latest paper, researchers at the ETH Zürich immobilized increasing consecutive numbers of an RNA tandem motifs on a switchSENSE® chip, which could be recognized by the RNA-binding protein RBFOX1/2 RRM. They found that with increasing number of binding motifs the affinity of RBFOX1/2 RRM increased significantly. This was attributed to a cooperative effect due to multiple protein molecules attaching to the DNA when more than one binding site was available.

In line with this, they could show by using the sizing function of the switchSENSE® technology that with increasing number of binding sites the relative size of the bound protein species increased, confirming the binding of multiple protein monomers.
