一种用于蛋白纯化的层析柱 A chromatography column for protein purification

[0001] [0001]

技术领域 FIELD

[0002] 本发明属于生物纯化器械,具体涉及一种用于蛋白纯化的层析柱。 [0002] The present invention belongs to the biological purification device, in particular to a chromatography column used for protein purification.

背景技术[0003]目前,多种化合物的组合物、天然产物及中药的分离纯化,主要是采用柱色谱,使用层析柱,通过柱层析过程来实现。 BACKGROUND OF THE INVENTION [0003] Currently, the composition of a variety of compounds, separation and purification of natural products and medicine, mainly by column chromatography using column by column chromatography procedures to implement. 传统的柱色谱是将混合化合物放置在玻璃柱柱床的顶端,使混合溶剂组成的洗脱剂(流动相)在重力作用下,通过装有吸附性介质材料(固定相)的垂直玻璃柱,分离得到各个较纯的产品(纯品),其原理是:由于混合化合物中各组分对色谱柱中固定相和流动相的亲和力不同,故根据混合化合物的性质选择合适的固定相和流动相,可以达到将其中各组分尽可能分离的目的,分离的产品在柱子出口分别被收集到各个收集瓶中,然后,鉴定各个收集瓶中的收集到的层析液,根据鉴定结果合并和浓缩各相同层析液,得到各个纯品。 Conventional column chromatography is to mix the compound placed on top of a glass column packed bed, the mixed solvent composition of the eluent (mobile phase) under gravity, through the dielectric material containing adsorbent (stationary phase) of a vertical glass column, each isolated pure product (pure), the principle is: Because each component of the mixed compound affinity column stationary and mobile phases are different, so choose the appropriate fixed and mobile phases depending on the nature of the mixed compound , which can achieve the purpose of the separation of the components as much as possible, the separation of the product were collected at the column outlet to the respective collection bottle, and then, the identification of each collecting vial collected liquid chromatography, based on the identification results combined and concentrated isotropic liquid chromatography to give each pure.

[0004] 常见层析柱根据压力不同可分为常压柱、中压柱和高压柱。 [0004] According to common chromatography atmospheric pressure can be divided into columns, medium pressure and high pressure column column. 常压柱在实际中用得最多,常常是自己根据需要采用不同材料的层析柱、装填不同的填料来实现目标物质的分离纯化。 In the actual atmospheric column most frequently used, often their own column using different materials needed, different filler loading to achieve separation and purification of the target substance. 玻璃层析柱又尤其常用,常包括柱体、活塞,有的还包括位于柱体上端的用于固定加液球的倒钩等。 Glass column also particularly popular, often including cylinders, pistons, and some also include the upper cylinder located barbs and other fixed dosing for the ball. 目前常见的玻璃层析柱存在如下不足:一方面,在玻璃层析柱的填料装填和被分离物质样品装填中,常常根据不同填料和不同物质采用不同的填料,样品比例,以利于在达到最佳分离效果的同时节约填料,而填料.样品的比例通常参照其体积比,但是目前常用玻璃柱没有刻度,常常需要操作人员凭经验目测或用其他度量工具进行测量,非常麻烦;另一方面,在层析过程中,常常需要掌握样品在分离介质即填料中的迁移速度,然后根据迁移速度进行流出液的速度调节,以利于在达到最佳分离效果的同时节约层析时间,但是目前的层析柱没有刻度,常常是在不同时间点对某个层析色带的位置用记号笔标记,这样的做法不够准确,同时标记笔所标记的记号可能会因为添加洗脱剂时的泄漏而被冲刷掉,需要再次标记,很不方便。 Existing common glass column following disadvantages: on the one hand, a glass column packed in packing and loading of the material sample are separated, often using different packing according to different fillers and different substances, the proportion of the sample in order to facilitate reaching the most Good separation while saving filler, and filler are usually referring to the proportion of the sample volume ratio, but there is no common scale glass columns, often require the operator to visually or measured empirically, very troublesome to use other measurement tools; on the other hand, In the chromatographic process, it is often necessary to grasp the sample separating medium i.e. filler migration speed, then the speed of the effluent in accordance with the migration speed adjustment, in order to facilitate optimal chromatographic separation while saving time, but the current layer No scale analytical column, often at different time points for a chromatography ribbon position marked with a marker, such an approach is not accurate enough, while marking pen marks of identification may be added as the eluent when the leak is washed away, you need to re-mark, which was very convenient.

[0005] 此外,目前的层析柱在进样时,样品溶液从层析柱顶端的中部直接流进柱体,容易造成柱体内填料飞溅至层析柱的内壁上。 [0005] In addition, the current column during injection, the sample solution flows into the cylinder from the middle of the top of the column directly, easily lead to the body of the column packing to the inner wall of the splash chromatography column. 由于层析用的填料常常是比较昂贵的,飞溅至内壁上的填料没有在层析中得到充分的利用,影响层析效果。 Since chromatography filler is often relatively expensive, splash onto the inner wall of the filler material has not been fully utilized in chromatography, chromatography impact effect.
