Abstract:
A method for producing a water soluble recombinant fusion protein from an exogenous gene and collecting a protein having an original amino terminal is provided to prevent insoluble precipitation of the recombinant protein and improve the secretion efficiency of the recombinant protein to cytoplasm outside or periplasm. A method for improving the secretion efficiency of a foreign protein comprises: a step of constructing a leader sequence containing N-region of the signal sequence and/or leader sequence of foreign protein, of which pI value is 9.90-11.28; a step of adjusting the distance of amino acid which makes an impact on pI value in the leader sequence; a step of constructing the leaser sequence, distance adjusting site, restriction enzyme recognition site and a polynucleotide coding fusion protein containing foreign protein; a step of inserting the constructed gene into an expression vector to produce a recombinant expression vector; a step of transforming a host cell with the recombinant expression vector; and a step of screening a transformant having high water-soluble expression.
Abstract:
A method for discrimination of individuals infected with lymphocystis disease virus(LCDV) or Paralichthys olivaceus individuals having resistance against lymphocystis disease virus is provided to produce of healthy individuals without virus infection, reduce lymphocystis disease occurrence rate by treating lymphocystis disease at an early stage, and selectively produce the excellent Paralichthys olivaceus individuals. A genetic marker for discrimination of fish individuals infected with lymphocystis disease virus has the nucleotide sequence of SEQ ID NO:10, wherein the genetic marker is amplified by a pair of primers having the nucleotide sequences of SEQ ID NO:1 and SEQ ID NO:2, specific to NIF/NLI interacting factor gene; and the fish is Paralichthys olivaceus. The method for discrimination of fish individuals infected with lymphocystis disease virus comprises the steps of: (i) extracting the DNA sample of fish to be discriminated; (ii) amplifying the DNA sample with the primer pair of SEQ ID NO:1 and SEQ ID NO:2; and (iii) analyzing the amplification of the NIF/NLI interacting factor gene that is specific to the infection of lymphocystis disease virus.
