不同亚型兔出血症病毒单克隆抗体的制备及抗原表位鉴定开题报告

摘要:

亚型兔出血症病毒(RHDV)是主要感染野兔的致命性病毒,其在国内野兔、家兔中被广泛发现。为了控制RHDV的传播和感染,需要建立有效的诊断和预防手段。本研究旨在制备不同亚型RHDV的单克隆抗体,并鉴定其抗原表位,为RHDV检测和疫苗研发提供理论依据。

首先采用RHDVCp抗原免疫BALB/c小鼠,制备单克隆抗体。通过ELISA筛选,获得5株高效、特异的单克隆抗体。进一步通过Westernblotting和间接免疫荧光法,证实了这些抗体对不同亚型RHDV的高效识别。随后,通过Peptidearray分析和毒株差异性研究,初步鉴定了抗原表位。结果表明,这些抗体的抗原表位主要位于RHDVCp蛋白的C端。

本研究制备了高效、特异的不同亚型RHDV单克隆抗体,并初步鉴定了其抗原表位。这些结果为RHDV检测和疫苗研发提供了理论依据,也为其他病毒的单克隆抗体制备和抗原表位分析提供了参考。
