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

关于免疫诊断方法—免疫标记技术的介绍
为提高抗原和抗体检测的敏感性，将已知抗体或抗原标记上易显示的物质，通过检测标记物，反映有无抗原抗体反应，从而间接测出微量的抗原或抗体。常用的标记物有酶、荧光素、放射性同位素、胶体金及电子致密物质等。这种抗原或抗体标记上显示物所进行的特异性反应称为免疫标记技术(immunolabelling te
