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.

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？

TE缓冲液 123

☆你大爷☆pgyn2021-07-29

TE缓冲液是Tris +EDTA缓冲液，这种缓冲液我们一般用作溶解剂或保持剂，主要是调控PH，TAE是一种电泳缓冲液，主要用于DNA分子的电泳。 TE组成浓度：10mM Tris-HCl 1mM EDTA PH=8.0 配制量：500ml 配制方法：量取下列溶液于500ml烧杯中 1M Tris-HCl Buffer PH=8.0 5ml 0.5M EDTA PH=8.0 1ml 向烧杯中加入约400mldd H2O均匀混合；将溶液定容到500ml后，高温高压灭菌；室温保存.
TAE是使用最广泛的缓冲系统。其特点是超螺旋在其中电泳时更符合实际相对分子质量（TBE中电泳时测出的相对分子质量会大于实际分子质量），且双链线状DNA在其中的迁移率较其他两种缓冲液快约10%，电泳大于13kb的片段时用TAE缓冲液将取得更好的分离效果，此外，回收DNA片段时也易用TAE缓冲系统进行电泳。TAE的缺点是缓冲容量小，长时间电泳（如过夜）不可选用，除非有循环装置使两极的缓冲液得到交换。 50×TAE Buffer 配制方法： 1. 称量Tris 242g，Na2EDTA.2H2O 37.2g 于1L烧杯中； 2.向烧杯中加入约800ml去离子水，充分搅拌均匀； 3加入57.1ml的冰乙酸，充分溶解； 4.加去离子水定容至1L后，室温保存。向左转|向右转

【求助】为什么我的SDSPAGE电泳时电泳缓冲液变浑浊呢?123

戀█重量█p82017-10-02

原因可能如下：
1. Buffer中离子浓度过大，甘氨酸或者Tris碱有可能疏忽多加了
2.没有加相应浓度的SDS
3.电泳周围温度高，也是一个原因

RNA电泳为什么要用MOPS缓冲液123

嗳情啖了﹎4142021-08-08

电泳缓冲液还有一个组分是EDTA（乙二胺四乙酸），加入浓度为1-2mmol/L，目的是螯合Mg2+ 等离子，防止电泳时激活 DNA酶，此外还可防止Mg2+离子与核酸生成沉淀。
此外，我们常常用“电泳法”判断液体的性质，是胶体还是溶液。在高中化学中我们就用过这种方法判断给定的液体是否为胶体。MOPS电泳缓冲液、胚胎干细胞培养生长因子、动物肝细胞分离培养试剂盒、结晶紫细胞群落染色试剂盒、MFN-2蛋白表达检测试剂盒、血红细胞溶解液、磷酸缓冲盐溶液、Hanks平衡盐粉剂、胰蛋白酶溶液、

离子强度是表示溶液中电荷数量的一种量度，等于溶液中各种离子的摩尔浓度与其价数平方之积总和的一半。
低离子强度时，迁移率快。但离子强度过低，缓冲液的缓冲容量小，不易维持pH恒定。高离子强度时迁移率慢，因此为了获得更快的反应速度，在缓冲容量允许的范围内，离子强度应该尽可能小。
