Our blogs and videos choice: solid phase dna synthesis

Purdue e-Pubs

To obtain these structures, a new, efficient solid-phase synthesis protocol was developed as well. To determine the binding affinity and selectivity of these compounds among all possible 4-base pair sequences of DNA, a high throughput (HT), fluorescence intercalator displacement (FID) assay was employed. The FID results indicate that these compounds are good DNA minor groove binders as predicted (more than 50% fluorescence decrease at 10 μM for A/T only sequences); the amidine group improves the binding affinity and selectivity compared to amino acid-benzimidazole conjugates without an [more...]

Development of a Novel Fluorescence Assay Based on the Use of the ...

Human -alkylguanine-DNA alkyltransferase (hAGT) is a DNA repair protein that reverses the effects of alkylating agents by removing DNA adducts from the position of guanine. ... Oligonucleotide synthesis was performed by the solid-phase - cyanoethyl-phosphoramidite method . Ammonia treatment was performed at room temperature overnight to minimize decomposition of O6-methylguanine. For the same reason, the dimethylformamidino group was selected for the protection of [more...]
