文题释义:
胶原(collagen
):是一种不透明、白色、无支链的纤维蛋白质,是动物体内分布最广,含量最多的蛋白质。胶原的科学定义为:“细胞外基质(ECM)的结构蛋白质,分子中至少应该有一个结构域具有α链组成的三股螺旋构象”。通俗的概念:不溶于冷水、热水,有三螺旋结构,保留生物活性。胶原与胶原蛋白不是一种物质,胶原蛋白又称水解胶原蛋白,是胶原经过水解后失去了三螺旋结构的产物。
非变性Ⅱ型胶原:是胶原的一种类型,所谓非变性是指其三螺旋结构没有被破坏。Ⅱ型胶原软骨中较为多见,参与软骨的新陈代谢,与某些疾病的发生发展有关,如类风湿关节炎及骨关节炎。


背景:非变性胶原实验室层面的纯化已有许多文献和研究,但中试和生产量级的提取和纯化的报道和文献较少。这种实用技术毕竟要走出实验室才有意义,到中试和生产阶段更多面临的是成本、得率、设备、操作便利度的衡量。 

目的:探讨解决非变性Ⅱ型胶原中试及生产中脱盐、脱酸纯化的工艺方法及条件。
方法:对统一制备的非变性Ⅱ型胶原分别按透析袋法、水洗法、甩滤法、中空纤维膜法4种方法进行纯化,通过得率、胶原含量、纯度3项指标对比4种方法在胶原纯化工艺的优缺点。
结果与结论:①得率:透析袋法最高;中空纤维膜法其次;第三为甩滤法;水洗法最低;②胶原含量:透析袋法最高,中空纤维膜法其次,第三为水洗法,甩滤法最低;③胶原纯度鉴定:4种方法没有显著性区别;④压力对通量的影响:存在正相关,但差别并不大;⑤结果表明,通过得率、胶原含量、胶原纯度、压力差与膜通量数值关系等指标的比较,认为中空纤维膜法在非变性Ⅱ型胶原提纯中具有比较优势。该研究的技术路线已在2013年5月1日取得国家发明专利,专利号ZL 2011 10065733.X,作者是该专利第一发明人。

Abstract:

BACKGROUND: Increasing studies have been concentrated on the purification of non-denatured collagen at the laboratory level, but there are fewer reports on the extraction and purification of pilot scale and production scale. After all, this technology has to be out of the laboratory to make sense. At the trial and production stages, more is faced with the measurement of cost, yield, and ease of operation.

OBJECTIVE: To explore the methods and conditions for the desalination and deacidification purification of non-denatured type II collagen in the pilot test and production.
METHODS: The commonly used desalination and deacidification methods for non-denatured type II collagen extracted included dialysis bag method, water washing method, rejection filtration method, and hollow fiber membrane method. The denatured type II collagen was purified according to these four methods. Disadvantages and advantages of the dialysis bag method, water washing method, rejection filtration method, and hollow fiber membrane method in the collagen purification process were compared using three indexes: yield, collagen content, and purity.

RESULTS AND CONCLUSION: For the yield, the ranking order was as follows: dialysis bag method > hollow fiber membrane method > rejection filtration method > water washing method; for the collagen content, dialysis bag method > hollow fiber membrane method > water washing method > rejection filtration method; for the purity of collagen, there was no significant difference among the four methods. Moreover, pressure was positively but insignificantly correlated with the membrane flux. By comparing the yield, collagen content, collagen purity, pressure difference, and membrane flux numerical value, it is considered that the hollow fiber membrane method has a comparative advantage in the purification of non-denatured type II collagen. This concludes that the hollow fiber membrane method is more suitable for industrial production, which has been patented on May 1, 2013 with national patent No. ZL 2011 10065733.X, and the authors are the first inventors of the patent.
