Abstract:
본 발명은 닭의 악성 전염병인 뉴캐슬병(Newcastle disease, ND) 진단에 관한 것이다. 상기와 같은 본 발명에 따르면, 뉴캐슬병 바이러스(Newcastle disease virus, NDV) HN(haemagglutinin-neuraminidase) 유전자를 포함하는 재조합 베큘로바이러스 발현벡터를 곤충세포에 형질감염시키고, 상기 곤충세포에서 발현된 NDV HN 단백질 및 이를 포함하는 혈구응집억제시험법(hemagglutination inhibition, HI법) 검사용 NDV 항원진단액을 제공함으로서, 살아있는 NDV를 취급하는 과정에서 발생할 수 있는 주변 오염이나 질병 전염의 위험성을 배제할 뿐만 아니라 신속하고 경제적인 방법으로 NDV 항원진단액을 대량생산할 수 있는 효과가 있다.
Abstract:
PURPOSE: An HN protein of Newcastle disease virus (NDV) and an NDV antigen diagnostic liquid containing the same for a hemagglutination inhibition (HI) method are provided to quickly and cheaply produce the NDV antigen diagnostic liquid without contamination or disease infection. CONSTITUTION: A method for preparing a recombinant baculovirus expression vector comprises the steps of: isolating virus genome RNA from NDV Lasota strain; synthesizing cDNA of HN protein of NDV protein using a reverse primer of sequence number 2 and RNA; performing PCR of cDNA using a forward primer of sequence number 1, and a reverse primer of sequence number 2 to synthesize DNA; treating the synthesized DNA with Xba1 and Hind III, and extracting DNA fragments; and inserting the DNA fragment into a multicloning site of pFastBac TM 1 expression vector with baculovirus polyhedron promoter.

Abstract:
PURPOSE: HN protein of avian paramyxovirus-4 (APMV-4) and an antigen diagnostic solution for HI method examination including the same are provided to be able to exclude the danger of neighbor contamination or disease contagion in the process of treating live APMV-4, and to be able to mass-produce the APMV-4 antigen and antibody diagnostic solution in a rapid and economic method. CONSTITUTION: A manufacturing method of an expression vector of recombinant baculovirus including HN gene of APMV-4 comprises (1) a step of extracting virus genome RNA from APMV-4 La Sota strain; (2) a step of synthesizing cDNA of HN protein gene of APMV-4 by using the extracted RNA and reverse primer of Sequence 2; (3) a step of amplifying the synthesized cDNA, forward primer of Sequence 1, and reverse primer of Sequence 2 by using PCR, and synthesizing DNA; (4) a step of extracting DNA fragment by treating the synthesized DNA with EcoR1 and Hind III; and (5) a step of inserting the extracted DNA fragment into the multicloning site of pFastBac^TM1 expression vector having baculovirus polyhedrin promoter (PPH). The forward primer of Sequence 1 is that EcoR1 restriction enzyme acting site is inserted into the upper part of ATG of 5' end terminal. The revers primer of Sequence 2 is that Hind III restriction enzyme acting site is inserted into the upper part of end codon of 5' end terminal.
