以人和牛晶状体醛糖还原酶、人胎盘醛还原酶I、醛还原酶II制备的抗血清,用DEAE-纤维素柱层析部分纯化的人组织中的醛糖还原酶和醛还原酶I、II,用免疫滴定的方法进行免疫化学鉴定。抗醛糖还原酶抗血清与醛还原酶I发生交叉反应,抗醛还原酶I抗血清与醛糖还原酶、抗醛还原酶II抗血清发生交叉反应。De-52洗脱图谱、底物特异性和免疫化学特征表明,醛糖还原酶存在于人的主动脉、脑、红细胞和肌肉中;醛还原酶I存在于人的肾脏、肝脏和胎盘中;醛还原酶II存在于人的脑、红细胞、肾脏、肝脏、肺和胎盘中。采用免疫亲和技术,从胎盘抗醛还原酶I抗血清中纯化出单特异性抗α和抗β抗血清。抗α抗血清可同时沉淀醛还原酶I和醛糖还原酶,而抗β抗体仅与醛还原酶I发生交叉反应。在此基础上,提出了三基因座模型来解释这些酶之间的遗传关系。醛糖还原酶是α亚基的单体,醛还原酶I是α和β亚基的二聚体,醛还原酶II是δ亚基的单体。
Immunochemical characterizations of aldose reductase and aldehyde reductases I and II, partially purified by DEAE-cellulose (DE-52) column chromatography from human tissues, were carried out by immunotitration, using antisera raised against the homogenous preparations of human and bovine lens aldose reductase and human placenta aldehyde reductase I and aldehyde reductase II. Anti-aldose reductase antiserum cross-reacted with aldehyde reductase I, anti-aldehyde reductase I antiserum cross-reacted with aldose reductase and anti-aldehyde reductase II antiserum precipitated aldehyde reductase II, but did not cross-react with aldose reductase or aldehyde reductase I from all the tissues examined. DE-52 elution profiles, substrate specificity and immunochemical characterization indicate that aldose reductase is present in human aorta, brain, erythrocyte and muscle; aldehyde reductase I is present in human kidney, liver and placenta; and aldehyde reductase II is present in human brain, erythrocyte, kidney, liver, lung and placenta. Monospecific anti-α and anti-β antisera were purified from placenta anti-aldehyde reductase I antiserum, using immunoaffinity techniques. Anti-α antiserum precipitated both aldehyde reductase I and aldose reductase, whereas anti-β antibodies cross-reacted with only aldehyde reductase I. Based on these studies, a three gene loci model is proposed to explain the genetic interrelationships among these enzymes. Aldose reductase is a monomer of α subunits, aldehyde reductase I is a dimer of α and β subunits and aldehyde reductase II is a monomer of δ subunits.
