  • Long-acting recombinant porcine FSH fusion protein and preparation method and application thereof
    Patent number: 11299527
    Abstract: Two long-acting recombinant porcine FSH (follicle-stimulating hormone) fusion proteins, comprising pFSH-Fc-1 and pFSH-Fc-2. ? subunit/? subunit is directly or indirectly fused on a Fc fragment by means of a linking component; the ? subunit/? subunit is combined with the ? subunit/? subunit by means of a Van der Waals force or the linking component. The porcine FSH fusion proteins can be prepared by an eukaryotic expression system based on a gene engineering technology. The two porcine FSH fusion proteins have a good medicinal effect and have a longer half-life period as compared with that of a natural porcine FSH; the two porcine FSH fusion proteins do not generate an undesirable effect on animals and can replace pregnant mare serum gonadotropin (PMSG) to be used in animal breeding production. The two porcine FSH fusion proteins can be used for preparation of medicines in the field of animal breeding.
