根据过去初步观察的结果,上皮性卵巢癌腹水提取物免疫家兔,制备抗血清,与上皮性卵巢癌患者血清作反向间接血凝试验,阳性率为63％,临床符合率达75％。在进一步研究中明确这种提取物是一种抗原抗体复合物,与Barber等报道符合。将此复合物提取后解离,可得到较纯的抗体及抗原。 According to the results of the preliminary observation in the past, the ascites extract of epithelial ovarian cancer was used to immunize rabbits to prepare antiserum and reverse hemagglutination test with sera from patients with epithelial ovarian cancer. The positive rate was 63% and the clinical coincidence rate reached 75%. In further studies, it is clear that this extract is an antigen-antibody complex, consistent with the report by Barber et al. After the complex is extracted and dissociated, relatively pure antibodies and antigens can be obtained.
