摘要 目的 探讨三氯醋酸-丙酮沉淀法提取骨组织蛋白的可行性和效率。方法 采用盐酸脱钙法和三氯醋酸-丙酮沉淀法,分别用于骨组织蛋白的提取,并对两种方法的提取效率进行对比。结果 三氯醋酸-丙酮沉淀法可获得较高的骨蛋白提取率,与盐酸脱钙法相比,分子条带分布范围相近,且不受骨髓造血组织影响。结论 三氯醋酸-丙酮沉淀法可以用于骨组织蛋白质组的研究。

AbstractObjective To explore the feasibility and efficiency of extracting protein from bone tissue using trichloroacetic acid (TCA)-acetone precipitation method. Methods Hydrochloric acid (HCL) decalcification method and TCA-acetone precipitation method were separately used for bone protein extraction. The efficiencies of these two methods were compared. Results TCA-acetone precipitation method had significantly higher extraction efficiency. Compared with HCL decalcification method, it had less pollution from bone marrow hematopoietic tissue. Protein band distribution was similar between these two methods. Conclusion TCA-acetone precipitation method is useful for bone proteomics research.
