Description
技术领域
本发明涉及生物芯片技术领域,具体为一种IMAC芯片的重生液配方。
背景技术
蛋白质芯片技术是一种操作简单,方便快捷,样本需要量少,敏感性高,特异性强,通量高的蛋白组学研究方法,在蛋白质功能分析、肿瘤标志物筛选、药物研发等方面具有广泛的应用前景,该技术根据层析技术,结合质谱发展而来,芯片为表面经过化学和生物修饰的可结合蛋白的固体点表面,IMAC蛋白质芯片表面固定有金属离子螯合剂,利用载体上的金属离子和蛋白质表面暴露的氨基酸残基之间的金属络合作用对蛋白质进行亲和纯化,对大肠杆菌表达包涵体蛋白质的分离及肿瘤标志物的发现具有良好的应用前景。
蛋白质芯片技术的一个关键因素就是蛋白芯片的选择,根据检测靶蛋白的不同性质,需要选择不同的蛋白芯片,从而特异性的结合待测蛋白而洗去非特异蛋白,降低检测背景,蛋白质芯片的使用频率理论上是一次性的,这样会大大增加芯片的使用成本。
为此,我们提出了一种IMAC芯片的重生液配方。
发明内容
针对现有技术的不足,本发明提供了一种IMAC芯片的重生液配方。
本发明提供如下技术方案:一种IMAC芯片的重生液配方,该重生液为终浓度250mM的乙二胺四乙酸钠溶液,pH值7.0。
优选的,该重生液的制备过程如下:
S1、将称量适合分量的乙二胺四乙酸钠73.06克;
S2、将73.06克乙二胺四乙酸钠,并缓慢加入大约1L去离子水,并不停的搅拌;
S3、待其溶解后,调整溶液pH值到7.0;
S4、将溶液过滤,即可得到重生液。
优选的,该重生液的使用方法:
S1、将IMAC芯片放入重生液中浸泡,并将由IMAC芯片的重生液放置在摇床中培养2个小时;
S2、之后将IMAC芯片取出放入纯化水中,并将其在置入摇床中培养1个小时;
S3、取出,通过空气干燥机,进行快速干燥,即可。
与现有技术对比,本发明具备以下有益效果:
该IMAC芯片的重生液配方,将IMAC芯片置入乙二胺四乙酸钠溶液中,经过两个小时的浸泡洗脱以后,可使IMAC芯片重新恢复,可以多次重复使用,从而降低芯片的使用成本。
附图说明
图1为本发明IMAC芯片结合原理图;
图2为本发明重生液使用效果图。
具体实施方式
为了使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例,都属于本公开保护的范围。
除非另外定义,本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同,而不排除其他元件或者物件。
为了保持本公开实施例的以下说明清楚且简明,本公开省略了已知功能和已知部件的详细说明,以避免不必要地混淆本发明的概念。
一种IMAC芯片的重生液配方,该重生液为终浓度250mM的乙二胺四乙酸钠溶液,pH值7.0。
该重生液的制备过程如下:
S1、将称量适合分量的乙二胺四乙酸钠73.06克;
S2、将73.06克乙二胺四乙酸钠,并缓慢加入大约1L去离子水,并不停的搅拌;
S3、待其溶解后,调整溶液pH值到7.0;
S4、将溶液过滤,即可得到重生液。
该重生液的使用方法:
S1、将IMAC芯片放入重生液中浸泡,并将由IMAC芯片的重生液放置在摇床中培养2个小时;
S2、之后将IMAC芯片取出放入纯化水中,并将其在置入摇床中培养1个小时;
S3、取出,通过空气干燥机,进行快速干燥,即可。
图1是使用过的芯片,可以看见芯片上有大量特异性结合的多肽分子,图2是同样的芯片经过重生液处理以后的结果,可以发现芯片上结合的多肽分子已经被完全洗脱下来,如此IMAC芯片重新恢复,可以使芯片多次重复使用,从而降低芯片的使用成本。
以上实施例仅为本发明的示例性实施例,不用于限制本发明,本发明的保护范围由权利要求书限定。本领域技术人员可以在本发明的实质和保护范围内,对本发明做出各种修改或等同替换,这种修改或等同替换也应视为落在本发明的保护范围内。
