血清及细胞膜上的5′—核苷酸酶活性定量测定法简单,快速、敏感,一般实验室可测,血清中此酶的定量测定能用于肝脏疾病的诊断。因淋巴细胞膜上结合有此酶,所以可用于白细胞亚群的临床检测及培养的淋巴细胞的测定,也能用于白血病及恶性淋巴瘤的研究。据报导,原发性低丙种球蛋白血症(CVK);几种联合性免疫缺陷病;T急性淋巴细胞性白血病、B慢性淋巴性白血病及其他B细胞疾病(例如:B急性淋巴性白血
Quantitative assay of 5’-nucleotidase activity on serum and cell membrane is simple, rapid and sensitive, and can be measured in general laboratories. The quantitative determination of this enzyme in serum can be used for the diagnosis of liver diseases. Due to the combination of this enzyme on the membrane of lymphocytes, it can be used for the clinical detection of leukocyte subpopulations and the determination of cultured lymphocytes, and also for the study of leukemia and malignant lymphoma. It has been reported that primary hypogammaglobulinemia (CVK); several combination immunodeficiency diseases; T acute lymphocytic leukemia, B chronic lymphocytic leukemia and other B cell diseases (eg, B acute lymphoid leukemia
