PrinciplesofAsepticTechnique——3
PREPARATION OF THE ANIMALThe animals should be prepared in a n area separate from where surgery will be performed. Preparation is facilitated by first inducing anesthesia. The stomach, rectum and urinary bladder can then be evacuated as required at this stage. Hair is then removed from the surgical site using elect ric clippers equipped with a fine blade. A liberal area is clipped to anticipate any enlargement of the......阅读全文

显微操作技术（micromanipulation－technique）
显微操作技术（micromanipulation technique）是指在高倍复式显微镜下，利用显微操作器（micromanipulator）进行细胞或早期胚胎操作的一种方法。显微操作器是用以控制显微注射针在显微镜视野内移动的机械装置。显微操作的基础平台--倒置研究级显微镜（例如OLYMPUS的I
沉淀反应技术(Precipitation－reaction－technique)
一、 概述 可溶性抗原（如细菌浸出液、含菌病料浸出液、血清以及其他来源的蛋白质、多糖质、类脂体等）与其相应的抗体相遇后，在电解质参与下，抗原抗体结合形成白色絮状沉淀，出现白色沉淀线，此种现象称为沉淀反应。沉淀反应中的抗原叫沉淀原（precipitinogen）,与沉淀原发生反应的抗体称为沉淀
免疫印迹技术(Immunoblotting－technique)
免疫印迹技术又称蛋白质印迹(Western blotting)是一种借助抗原鉴定特异性抗体的有效方法，该法是在凝胶电泳和固相免疫测定技术基础上发展起来的一种新的免疫生化技术。本实验以检测可提取性核抗原(ENA)抗体为例。【实验原理】先将ENA混合抗原经SDS-PAGE电泳，使各种抗原成分根据分子量不

免疫荧光技术(immunofluorescence－technique)1
免疫荧光技术(immunofluorescence technique)是一种以荧光物作为标记物的免疫分析技术，荧光物质分子在特定条件下吸收激发光的能量后，分子呈激发态而极不稳定，其迅速回到基态时，可以电磁辐射形式释放出所有的光能，发射出波长较照射光长的荧光。用荧光素与已知的抗体（或抗原，较少用
