  • Patent number: 11505800
    Abstract: A method for improving a bio-coupling efficiency between a protein and a nucleic acid based on an ?-helix handle includes the following steps. First, the handle carrying the non-natural amino acid (H-tag) is designed. Then, a recombinant expression plasmid encoding a fusion protein containing the H-tag and the protein to be tested is constructed. Subsequently, the fusion recombinant protein containing the non-natural amino acid in the H-tag is expressed and purified. Finally, the non-natural amino acid in the H-tag-fused protein and the coupling group on the nucleic acid substrate are efficiently connected by click chemistry. Thea-helix handle is used to provide a controllable reaction condition on the protein surface for the non-natural amino acid, avoiding the complex structure, charge and polar nanoenvironment around the surface of the protein to be tested.

  • Publication number: 20200048452
    Abstract: The invention is a polyoxymethylene film and a preparation method. The polyoxymethylene film comprises: 96 to 98 parts by weight of polyoxymethylene resin, 0.5 to 2 parts by weight of nucleating agent, 0.5 to 1 parts by weight of antioxidant, and 0.5 to 1 parts by weight of formaldehyde absorbent. In view of the high crystallinity and fast crystallization rate of polyoxymethylene, blown film process is used to directly blowing the molten mass extruded through a die of a screw extruder to form a blown film bubble. It is easy to form thin neck and easy to break when stretching, so the method is beneficial to form polyoxymethylene film, and has high processing efficiency, and is suitable for industrialization. Copolymerization unit —CH2—CH2—O— is introduced into the molecular chain of polyoxymethylene and its ratio is increased, thereby effectively reducing the crystallization rate of the materials and making it easier to form a film.
