Scientific Background | HSP90 is a highly conserved and essential stress protein that is expressed in all eukaryotic cells. From a functional perspective, HSP90 participates in the folding, assembly, maturation, and stabilization of specific proteins as an integral component of a chaperone complex (1-4). Despite its label of being a heat-shock protein, HSP90 is one of the most highly expressed proteins in unstressed cells (1–2% of cytosolic protein). It carries out a number of housekeeping functions – including controlling the activity, turnover, and trafficking of a variety of proteins. Most of the HSP90-regulated proteins that have been discovered to date are involved in cell signaling (5-6). The number of proteins now know to interact with HSP90 is about 100. Target proteins include the kinases v-Src, Wee1, and c-Raf, transcriptional regulators such as p53 and steroid receptors, and the polymerases of the hepatitis B virus and telomerase (5). When bound to ATP, HSP90 interacts with co-chaperones Cdc37, p23, and an assortment of immunophilin-like proteins, forming a complex that stabilizes and protects target proteins from proteasomal degradation. In most cases, HSP90-interacting proteins have been shown to co-precipitate with HSP90 when carrying out immunoadsorption studies, and to exist in cytosolic heterocomplexes with it. In a number of cases, variations in HSP90 expression or HSP90 mutation has been shown to degrade signaling function via the protein or to impair a specific function of the protein (such as steroid binding, kinase activity) in vivo. Ansamycin antibiotics, such as geldanamycin and radicicol, inhibit HSP90 function (7). For more information visit our HSP90 Scientific Resource Guide at http://www.HSP90.ca. |

是否可以理解为纯化水得PH范围为6.3-7.6?能否直接用pH计测量?谢谢!
常用流动相加酸碱后PH的总结,希望大家能够提供一点自己测过的结果,谢谢先
两个CEX方法A和B测定同一单抗,结果碱性峰比例差不多,酸性峰比例相差约7%,相应主峰也差了7%左右。
具体来说,A方法酸性峰高,主峰低,碱性峰稍微低点;B方法酸性峰低,主峰高,碱性峰稍微高点;另外也做了CIEF,结果呢和A方法更接近。
仔细比较起来,AB两个方法的峰性和数量差不多,就不知道为什么会有这么大的差异。两个方法一个用的WCX柱-磷酸缓冲液,一个用SCX柱-MES缓冲液
大家帮我分析下:
1.两个方法哪个方法更准确,是以酸性峰高的为准还是什么?为什么?
2.这显著差异是由方法造成,具体原因是什么?柱子?
3.CIEF的结果和A方法更接近,是不是可以由此证明A方法更好或者CIEF的方法更好(因为CIEF更快更方便)?
欢迎讨论~
纠正下,A方法用的是Tosoh的柱子,B方法用的是SCX柱。TOSOH的柱子是7um的填料,10cm长。SCX是10um的填料。我本人TOSOH的阳离子柱子用的很少,这次信手用用,结果发现差异很大
那我现在就考虑,在以后方法开发过程中,除了通过流动相pH和组成、梯度、柱子选择来获得样品主峰和酸碱性的最大分离,还要关注各峰比例。因为之前比较方法好坏都只看分离度,尤其是主峰和邻近峰的分离度,获得最大分离度,自然可以做到主峰尽可能纯,但从未认真比较过各峰比例。这是一个大疏忽吧!
另外,CIEF和CEX方法原理还是有点差异的,所以分的是不同的异质体,原液放行两个方法肯定是都要做的。问题就是在早期细胞株筛选和工艺开发阶段,哪个方法才是又快又准。CIEF(iCE280)一般15分钟一个样,比CEX快多了。如果CIEF测得主峰要低于CEX结果,是不是真的完全可以取代CEX呢?CEX分离出的峰远比CIEF的多!
欢迎大家继续讨论~
因为是考察不同PH对药物的影响,样品又不好改变其PH值,这种情况怎么办?希望有经验的高手指教。
我的流动相是甲醇-水(90:10)
谢谢赐教!
请进子版按格式发贴,自行修改,谢谢。
这就是说不用酸碱预处理吗?
