Abstract: A dendritic polymer contains a dendritic polyester as a core, and a plurality of arms obtained by means of polymerization of an alkenyl monomer. The root-mean square radius of gyration of the dendritic polymer does not exceed 100 nm. The alkenyl monomer contains a non-ionic monomer and an anionic monomer. The polymeric segments formed by a monomer generally used for synthesizing a filtrate loss reducer are used as the arms of the dendritic polymer, which is obtained by means of free radical polymerization. Compared with a linear polymer having an identical molecular weight, the dendritic polymer has a smaller root-mean-square radius of gyration and is more compact in structure. suitable for use in a drilling fluid.

Abstract: Disclosed are a PAM restriction-free adenine base editor fused protein and use. A mutant polypeptide is provided, which comprises an N-terminal fragment of SpRY(D10A), a TadA8e fragment, and a C-terminal fragment of SpRY(D10A) polypeptide in sequence from the N terminus to the C terminus. A fused protein including the mutant polypeptide can target the whole genome, thereby broadening the editable range of the genome. It can induce a base transition of A:T to G:C more efficiently, and has great use potential, including but not limited to, simulation or correction of pathogenic sites in genetic disorders. It lowers off-target at the transcriptome level, and is a mutant form with high efficiency and low off-target.
