摘要: 白蛋白是血清的重要组成成分,是一种高水溶性的球状蛋白质,可以维持血浆胶体渗透压平衡,兼具抗凝和抗氧化作用。血清白蛋白(serum albumin,SA)的化学结构和构象允许其与许多药物结合,影响药物的转运和代谢过程。作为内源性和外源性配体的载体蛋白,SA对于多种疾病的治疗具有重要的临床意义,包括失血性休克、低白蛋白血症、慢性肝病等。同时,SA还可以作为细胞培养剂,影响卵母细胞的体外成熟和冷冻精子的活性,在动物生产中发挥重要作用。因此,SA的需求在世界范围内逐年增加,获得高纯度、高活性、高回收率的SA至关重要。目前,SA的纯化工艺包括冷乙醇提取法、亲和沉淀、三氯乙酸/丙酮沉淀法、硫酸铵沉淀结合液相色谱法、Cohn法结合液相色谱法、色谱法。作者综述了SA的结构、生理功能、应用及纯化工艺研究进展,并总结不同纯化工艺的原理、纯化效果及优缺点,明晰SA的提取及纯化工艺进程,以期为SA的深入研究和开发利用提供理论依据,进一步推动SA在医药、分子生物学研究、免疫诊断等领域的应用。

Abstract: Albumin is an important component of serum.It is a highly water-soluble globular protein, which can maintain the balance of colloid osmotic pressure and has both anticoagulant and antioxidant effect.Serum albumin (SA) chemical structure and conformation allows interaction with many different drugs, affecting drugs transport and metabolic processes.As a protein carrier for endogenous and exogenous ligands, SA is of great clinical significance to be used to treat a variety of diseases, including hemorrhagic shock, hypoalbuminemia, chronic liver disease, etc.At the same time, it plays an important role in animal production by acting as cell culture agent, influencing the in vitro maturation of oocytes and the viability of frozen sperm.Therefore, the demand for SA increased annually worldwide, and it is crucial to obtain SA with high purity, high activity and high recovery.Currently, the purification process of SA includes ethyl alcohol precipitation, affinity precipitation, trichloroacetic acid/acetone precipitation method, ammonium sulfate precipitation combined with liquid chromatography, Cohn method combined with liquid chromatography, and chromatography.In order to clarify the extraction and purification process of SA, the structure, physiological functions, applications and purification processes of SA were reviewed in this paper, and the principles, purification effect, advantages, disadvantages of different purification processes were summarized.It was expected to provide a reference for the in-depth research, development, and utilization of SA, and further promotes the application of SA in the fields of medicine, molecular biology research and immuno-diagnostics.
