抗体的实际应用包括:(1) 测定体液中药物、激素、蛋白或酶的浓度;(2)在体内对组织或器官进行定位;(3)逆转药物或激素的效应,(4)改变器官的功能,例如受体阻滞。应用肌凝蛋白特异性抗体显影心肌梗塞属于第二类的应用。正常心肌细胞有完整的细胞膜,大分子不能穿透至细胞中,梗塞心肌的心肌细胞膜破裂,大分子可透过细胞内。心肌梗塞诊断中常规测定的血浆肌酸磷酸激酶、谷草转氨酶以及其他的酶,就是从细胞内弥漫到细胞外
Practical applications of antibodies include: (1) determining the concentration of a drug, hormone, protein, or enzyme in a body fluid; (2) locating a tissue or organ in the body; (3) reversing the effects of the drug or hormone; (4) Features, such as receptor block. The application of myosin-specific antibodies to develop myocardial infarction is a second category. Normal cardiomyocytes have a complete cell membrane, macromolecules can not penetrate into the cell, myocardial infarction myocardial cell membrane rupture, macromolecules can penetrate the cell. Plasma creatine phosphokinase, aspartate aminotransferase, and other enzymes routinely measured in the diagnosis of myocardial infarction are those that diffuse from the cell to the outside of the cell
