摘要: 作者制备兔抗牛IgG酶结合物,以提供ELISA法准确鉴定蚊胃血中的牛血,检测牛、马、羊、鸡、猪、兔、鼠7种动物及人血清。证明酶结合物具有很高的特异性及敏感性,数十次ELISA测定结果表明,牛血清稀释度为1:100时,OD值在1.2~1.9之间,平均值为1.42,其它6种动物及人血清则在0~0.08之间,平均值0.01~0.06。此稀释度不但在酶联免疫检测仪中显示出明显的特异性,而且用肉眼也很容易识别和判断。

Abstract: A enzyme-linked immunosorbent assay (ELISA)test was studied for detection of blood-meals in haematophagus mosquitoes.The conjugates of rabbit antibovine IgG were tested on serums of bovine,horse,goat,chicken,pig,rabbit ,mice and human;and more than the replicates of tests showed that the conjugates were proved both sensitive and specific.The conjugates were used at dilution of 1:100 and showed an average OD value of 1.42 while the serums from the six different animals showed an average OD value of only 0.01-0.06.The results indicate that the dilutions of 1:100 are not only high specific to detect with ELISA reader,but also easy to read by the naked eye.
