  • Patent number: 11267863
    Abstract: Disclosed are a novel N-terminal fusion partner, a fusion polypeptide including the fusion partner and a target polypeptide, and a method for producing a target polypeptide using the same. The novel fusion partner can enhance the yield of a target polypeptide (recombinant polypeptide) compared to the conventional fusion partners. Using the novel fusion partner is particularly beneficial in producing a target polypeptide having a relatively low molecular weight and an easily degradable amino terminus based on genetic recombination technologies. Further, the novel fusion polypeptide including the fusion partner can be expressed as inclusion bodies in a host cell and protected against proteases or the like in a host cell, which makes the target polypeptide produced stably. Therefore, in comparison to the conventional fusion partners, the novel fusion partner can be used to provide a method for producing a recombinant peptide with improved stability and yield.

  • Patent number: 10711049
    Abstract: The present disclosure relates to a method for producing a TLR5 agonist protein. According to the present disclosure, the TLR5 agonist protein can be easily separated and purified after biotechnological production. In particular, the fusion partner used for separation and purification is effectively removed so as to minimize the possibility of inhibiting binding to TLR5 and inducing an immune response by the fusion partner.

  • Publication number: 20100317248
    Abstract: Fabrics including a low-melting fiber are provided. In an embodiment, the fabric includes a regular fiber and a low-melting fiber. The low-melting fiber is directly included in either warps or wefts or both. Alternatively, a blended or plied fiber of the regular fiber and the low-melting fiber is included in either warps or wefts or both. The low-melting fiber has a fusion rate of 30 to 100%. The fabric has a yarn slip length of 0.1 to 2.5 mm.

  • Publication number: 20100151756
    Abstract: Screen fabrics are provided. In an embodiment, the screen fabric includes a regular fiber and a dope dyed fiber. The dope dyed fiber is directly included in either warps or wefts or both. Alternatively, a blended or plied fiber of the regular fiber and the dope dyed fiber is included in either warps or wefts or both. Differences in the lightness, chroma and hue of the screen fabric before and after post-processing are ±2 or less, ±2 or less and ±0.1 or less, respectively.
