本文用间接免疫酶标技术对大鼠Morris_(7777)肝癌细胞核抗原(非组蛋白[NP]-DNA复合物)进行组织化学免疫定位。采用酸性乙醇处理可有效地消除内源酶活力的干扰,但不影响组织抗原物质的免疫活性。
In this study, we used immunohistochemical technique to detect the expression of Morris7777 hepatocarcinoma cell nuclear antigen (non-histone protein [NP] -DNA complex) by immunohistochemistry. Acidic ethanol treatment can effectively eliminate the interference of endogenous enzyme activity, but does not affect the immune activity of the tissue antigenic substances.
