摘要:

背景:由于树鼩是介于食虫目和灵长目之间的代表,进化程度高,较价廉的灵长类动物,医学生物学的用途很高,已受到广大学者的重视。
目的:检测通常用的二抗能否与树鼩的血清发生免疫反应。
方法:用Western和ELISA的方法检测树鼩的血清是否与抗兔、抗羊、抗人、抗小鼠、抗大鼠、抗猴的二抗发生交叉反应。
结果与结论:Western结果表明树鼩的血清与抗兔、抗羊、抗人、抗小鼠、抗大鼠的二抗均不发生反应,与抗猴的二抗有交叉反应。ELISA的结果也表明树鼩的血清与抗猴的二抗有交叉反应,而与其他二抗没有交叉反应。结果说明通常卖的二抗不能用于树鼩IgG的免疫检测,只有抗猴的二抗与树鼩的血清发生交叉反应,必需制备抗树鼩IgG的单克隆和多克隆抗体,在没有现成抗体可用时,可采用抗猴的二抗替代检测,能在树鼩疾病动物模型的研究中得到广泛应用。

Abstract:

BACKGROUND: Tree shrew is a representative between insectivore and primates, has a high degree of evolution, is more inexpensive primates, has high use of medical biology, and has been attached by scholars.
OBJECTIVE: To detect whether the commonly used secondary antibodies have immune response with tree shrew serum.
METHODS: Western blot assay and enzyme linked immunosorbent assay were utilized to detect whether the tree shrew serum had cross-reacts with anti-rabbit, anti-goat, anti-human, anti-mouse, anti-rat, and anti-monkey secondary antibodies.
RESULTS AND CONCLUSION: Western blot assay results indicated that tree shrew serums did not react with anti-rabbit, anti-goat, anti-human, anti-mouse, and anti-rat secondary antibodies and had cross reaction with anti-monkey secondary antibody. Enzyme linked immunosorbent assay results also indicated that tree shrew serums were cross-reactive with anti-monkey secondary antibody, but did not have cross-reactivity with the other secondary antibodies. Above data confirmed that the usually soled secondary antibody cannot be used to immunoassay with tree shrews IgG. Only anti-monkey secondary antibody has cross-react with tree shrew serum. It is necessary to prepare anti-tree shrew IgG monoclonal and polyclonal antibodies. When no antibody is readily available at present, anti-monkey secondary antibody can be used to substitute detection, and can be widely applied in the study of tree shrew models of disease.
