本文研究了乳腺癌组织提取物和病人血清中ras癌基因产物p21蛋白的表达.结果表明良性乳腺瘤与恶性乳腺癌之间有明显差异.使用双抗体夹心法测定组织提取物和体液p21蛋白浓度是有效的.乳腺癌病人体液中p21蛋白含量较低,并且与健康人差异较小.
This article studied the expression of ras oncogene product p21 protein in breast cancer tissue extracts and patient serum. The results showed significant differences between benign breast adenomas and malignant breast cancers. The concentration of p21 protein in tissue extracts and body fluids was determined by double antibody sandwich method. It is effective. The level of p21 protein in body fluid of breast cancer patients is low, and it is less different from healthy people.
