本文测定了人肝天冬氨酸氨基转移酶（EC 2.6.1.1）活性及其同工酶的分布。兔抗猪蛋白可溶性抗血清（即，非线粒体）酶与人源的可溶性酶交叉反应，并用于免疫沉淀测定以定量可溶性和线粒体同工酶。这些被分离的快速，半定量电泳醋酸纤维素和其他三个定量技术：等电聚焦和阴离子和阳离子交换色谱。正常成人肝线粒体酶平均占总活性的81%（n = 4）。在人胎肝（总活性的56%）和肝母细胞瘤组织（38%）的单个标本中，其贡献显著降低。总酶活性（μ mol min-1每克组织）分别为：成人，150;胎儿，38;肿瘤，6。发现的总酶浓度（微摩尔酶/千克组织）为：成人，10.8;胎儿，2.7;肿瘤，0.4。将人肝脏中的浓度和同工酶分布与各种动物模型系统中的浓度和同工酶分布进行比较。本文综述了其他同工酶定量测定方法及其在血清浓度测定中的适用性。
Aspartate aminotransferase (EC 2.6.1.1) activity and the distribution of its isoenzymes in human liver were examined. Rabbit antiserum against porcin soluble (i.e., non-mitochondrial) enzyme cross-reacted with the soluble enzyme of human origin and was used in an immunoprecipitation assay to quantitate the soluble and mitochondrial isoenzymes. These were separated by rapid, semiquantitative electrophoresis on cellulose acetate and by three other quantitative techniques: isoelectric focusing and anion-and cation-exchange chromatography. The mitochrondrial enzyme averaged 81% of the total activity in normal adult human liver (n = 4). Its contribution was dramatically reduced in single specimens of human fetal liver (56% of total activity) and hepatoblastoma tissue (38%). Total enzyme activities (mumol min-1 per gram of tissue) were: adult, 150; fetal, 38; tumor, 6. Total enzyme concentrations (micromoles of enzyme per kilogram of tissue) found were: adult, 10.8; fetal, 2.7; tumor, 0.4. The concentrations and isoenzyme distribution in human liver are compared to those in various animal model systems. Other methods for quantitative estimation of the isoenzymes and their adaptability for use in estimating concentrations in serum are reviewed.
