为了获得人脱氧核糖核酸酶I(DNase I)作为免疫原,我们开发了一种比传统方法更有用和有效的方法,该方法以人尿为起始原料。在新的方法中,我们培养了携带人DNase I基因的表达载体的COS-7细胞,并从培养上清液中纯化了该酶。这种酶只需通过三个色谱柱就可以很容易地分离出来,达到明显的均一。我们用来对抗重组DNase I的兔抗血清在识别DNase I表型和中和酶活性方面都不逊于人尿中的DNase I。因此,我们的方法可能有助于生产针对人DNase I的抗体。
To obtain human deoxyribonuclease I (DNase I) as an immunogen, we have developed a procedure that is more useful and effective than the conventional procedure, which uses human urine as a starting material. In the new procedure, we culture COS-7 cells transfected with expression vector carrying human DNase I cDNA, and then purify the enzyme from the culture medium. The enzyme can be easily isolated to apparent homogeneity by passage through only three chromatography columns. The rabbit antiserum that we used against the recombinant DNase I was not inferior to that used against DNase I from human urine, in terms of both its ability to discriminate DNase I phenotypes and its ability to neutralize enzyme activity. Therefore, our procedure may be useful for producing an antibody specific for human DNase I.
