In addition to the four common bases, DNA also has various chemical modifications, such as cytosine methylation modification, hydroxymethylation modification, aldehyde modification, adenine methylation modification, etc.Deoxyuracil (dU) is a DNA modified base, which can be formed from cytosine-amidamidine under the action of deaminase or from the misincorporation of dUMP during...

5-methylcytosine modification (5mC) is one of the important epigenetic modifications in eukaryotic cell genomes. 5mC can be gradually oxidized under the action of TET family enzymes to generate 5-hydroxymethylcytosine (5hmC), 5-aldehydecytosine (5fC) and 5-carboxycytosine (5caC); for the above-mentioned several new DNA modifications Functional research is currently a hot spot in...

Polyamide-amine (PAMAM) polymer materials are a type of highly branched, "all-rounder" dendrimers with specific three-dimensional structures and highly controllable molecular size and configuration. Its unique molecular structure and physical and chemical properties make it widely used in biomedicine sustained release, genetic material carrier, surfactant, environmental pollution treatment, etc. It is...

Optically active binaphthyl and its derivatives can be used as excellent chiral ligands for a variety of asymmetric catalytic reactions. As a result, the study of binaphthyl chiral ligands and catalysts has gradually become a research hotspot among organic chemists. Bailingwei sells a new chiral binaphthyl catalyst developed by researcher...

Polysulfamide is a linear polymer with selective metal (palladium) adsorption capacity. The research group of Professor Yi Wenbin of Nanjing University of Science and Technology has developed a general method for preparing polysulfamide using secondary amines, and uses palladium to assist the synthesis of polysulfamide. A palladium-crosslinked polysulfamide skeleton metal...
