PrinciplesofAsepticTechnique
INTRODUCTIONThe regulations promulgated to implement the amended Animal Welfare Act require that all survival surgery be performed using aseptic procedures. This includes the use of surgical gloves, masks, sterile instruments and aseptic technique.In this chapter, the Principles of Aseptic Technique will be discussed with the emphasis on the practical application of these principles in the laboratory set ting.

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
