Abstract:
PURPOSE: A baculovirus expression vector system using a recombinant virus bEasyBac is provided to enhance separation efficiency of the recombinant virus and to enable high-throughput of the recombinant virus. CONSTITUTION: A baculovirus expression vector system simultaneously produces a large amount of foreign gene-introduced recombinant virus and is bEasyBac(deposit number:KCTC 11499BP). The foreign gene is EGFP gene and is inserted in to a transfer vector pDualBac(5,964 bp). The expression system has Kanamycin resistant gene and mini F replicon. The expression system contains a lethal gene isolated from Bacillus amyloquefaciens and ORF 3005 promoter.
Abstract:
PURPOSE: A recombinant virus bEasyBac is provided to enhance isolation efficiency of recombinant virus and to produce a large amount of recombinant virus. CONSTITUTION: A baculovirus expression vector system is able to produce a large amount of recombinant virus in which various foreign genes are introduced. The baculovirus expression system is bEasyBac(deposit number : KCTC 11499BP) which is not able to proliferate in an insect cell line. A method for preparing the recomnbinant virus bEasyBac comprises: a step of preparing recombinant virus vApLaZ by co-transfection of DNA of pBac8-LacZ with bApGOZA DNA in sf9; a step of performing co-tranfection of plasmid pTen-MF DN to sf9 to obtain homologous recombinant virus bTenLacZ; a step of inducing transposition with plasmid pDPNR-3005 ProBarnase DNA; and a step of performing eletroporation to E.coli DH10B.
Abstract:
PURPOSE: A novel porcine reproductive and respiratory syndrome virus(PRRSV) is provided to research of replication, transcription, and translation mechanism of PRRSV and develop diagnosis reagent and apparatus. CONSTITUTION: A DNA fragment encoding structure protein of porcine reproductive respiratory syndrome virus(PRRSV) is denoted by sequence number 1. The DNA fragment is denoted by sequence number 2, 3, 4, 5, 6, or 7. A vaccine composition for introducing antibody to PRRSV contains a polypeptide encoding with DNA fragment sequence.
Abstract:
PURPOSE: A gene sequence encoding glycoprotein gB, gC, and gD of swine Aujeszky's disease virus(ADV) is provided to develop virus vaccine and diagnosis reagent and apparatus and to prevent miscarriage of pregnant pig. CONSTITUTION: A DNA fragment encoding glycoprotein gB of swine Aujeszky's disease virus(ADV) NYJ(KCTC 11132BP) has a base sequence of sequence number 1. A DNA fragment encoding glycoprotein gC of swine Aujeszky's disease virus(ADV) NYJ(KCTC 11132BP) has a sequence of sequence number 2. A DNA fragment encoding glycoprotein gD of swine Aujeszky's disease virus(ADV) NYJ(KCTC 11132BP) has a sequence of sequence number 3. A polypeptide encoded by the DNA fragment has amino acid sequences of sequence number 4(gB), 5(gC), and 6(gD).
