目的:提取较纯的hTPO,为甲状腺激素合成过程的研究和建立hTPOAb检测方法提供了实验材料。方法:本文采用胰蛋白酶和脱氧胆酸钠处理手术切除人甲状腺组织,经超速离心和SephacrylS-300柱层析提纯人甲状腺过氧化物酶(hTPO),并进行了愈创木酚氧化法hTPO酶活性测定。结果:本研究获得的hTPO比生物活性为8.43愈创木酚单位(GU)/mg。经SDS-PAGE电泳鉴定示提纯的hTPO在分子量107kD处有一清晰色带,而于93kD处也有一色带,但较浅。结论:该方法提纯hTPO操作简便、快速,获得的hTPO较纯。
OBJECTIVE: To extract relatively pure hTPO and provide experimental materials for the study of thyroid hormone synthesis and the establishment of hTPOAb detection method. Methods: Human thyroid tissue was excised by trypsin and sodium deoxycholate. Human thyroid peroxidase (hTPO) was purified by ultracentrifugation and Sephacryl S-300 column chromatography. The effects of guaiacol oxidase hTPO enzyme Activity assay. Results: The specific bioactivity of hTPO obtained in this study was 8.43 guaiacol units (GU) / mg. The purified hTPO was identified by SDS-PAGE electrophoresis as a clear band at a molecular weight of 107 kD and a band at 93 kD, but lighter. Conclusion: This method is simple and rapid to purify hTPO. The obtained hTPO is more pure.
