Scientific Background	C-X-C chemokine receptor type 4 (CXCR-4) is a protein that in humans is encoded by the CXCR4 gene, also known as fusin or CD184 (cluster of differentiation 184). Chemokines and their receptors direct migration of distinct leukocyte subsets to sites of inflammation and to their specific niches in lymphoid organs. Virtually all T cell chemoattractants selectively attract memory/activated T cells. C-X-C chemokine receptor type 4 is involved in haematopoiesis and in cardiac ventricular septum formation. Plays also an essential role in vascularization of the gastrointestinal tract, probably by regulating vascular branching and/or remodeling processes in endothelial cells. It has been associated with WHIM syndrome. WHIM like mutations in CXCR4 were recently identified in patients with Waldenstrom's macroglobulinemia, a B-cell malignancy.

电泳分离四种核苷酸时,通常将缓冲液调到什么pH?此时它们是向哪极移动...123

阿瑟6102021-08-09

① 电泳分离4种核苷酸时应取pH3.5 的缓冲液，在该pH时，这4种单核苷酸之间所带负电荷差异较大，它们都向正极移动，但移动的速度不同，依次为：UMP>GMP>AMP>CMP；
　　② 应取pH8.0，这样可使核苷酸带较多负电荷，利于吸附于阴离子交换树脂柱。虽然pH 11.4时核苷酸带有更多的负电荷，但pH过高对分离不利。
　　③ 当不考虑树脂的非极性吸附时，根据核苷酸负电荷的多少来决定洗脱速度，则洗脱顺序为CMP>AMP> GMP > UMP，但实际上核苷酸和聚苯乙烯阴离子交换树脂之间存在着非极性吸附，嘌呤碱基的非极性吸附是嘧啶碱基的3倍。静电吸附与非极性吸附共同作用的结果使洗脱顺序为：CMP> AMP > UMP >GMP。

SDSPAGE电泳相关溶液的配置123

qinhuan04252021-08-01

最近刚开始跑SDS-PAGE，很奇怪，加样后，Marker和样本停在加样孔不往下面跑！且跑电泳时，电压（80V）一直上不去，后测电泳液PH值，不到8.0，这是主要原因吗？

如需调PH，是用NaOH吗？

电泳缓冲液浓度对实验时间有影响吗123

才子不才00022017-10-02

电泳缓冲液浓度对实验时间有影响。（如下案例）试验在20-40mmol/L范围内考察了醋酸铵浓度对4中组分分离度的影响。结果发信啊4中组分的迁移时间随醋酸铵浓度的增大而延长，从而分离度得到改善。但是缓冲液浓度越大分析时间也越长，如图3-3所示。向左转|向右转

问个关于电泳缓冲液的问题，如果用TBE作为缓冲液来做胶，然后用TAE来作为缓冲液来跑胶，或者是倒过来，电泳结果会不会有什么变化？

没什么实质性的差别。制胶、作为电泳缓冲液都可以。不过作为电泳缓冲液时，0.5×TBE更容易变热。

如果你是制胶或者做电泳缓冲液的话，不用灭菌。

【求助】几种蛋白电泳缓冲液的异同以及PVDF转膜过程中缓冲液要...123

目前常用的SDS-PAGE电泳缓冲液有：
Tris-Glycine/SDS;
MOPS/SDS;
Bis-Glycine/SDS等不同的缓冲液、预混液等。
不知道这几种缓冲液有什么异同呢？
比如如果是Invitrogen的预制胶-预混液电泳系统，每种预制胶有适配缓冲液，但是如果用其他的缓冲液似乎也可以得到不错的结果，那么是否说明电泳缓冲液只要满足了缓冲ph范围，其他的不是特别重要呢？
此外，附加提问是，PVDF膜在转膜的时候，转膜缓冲液中不需要加入甲醇，那么是加入甲醇转膜效果好还是不加好呢？
谢谢！
