Scientific Background	Chapsyn-110, is a part of the membrane-associated putative guanylate kinase (MAGUK) family. It binds directly to the NMDA receptor, and Shaker K+ channel subunits, and is 70-80% identical to PSD-95/SAP90 and SAP97 (1). It associated tightly with the postsynaptic density I brain, and mediates the clustering of both NMDA recpetors and K+ channels in heterologous cells. The encoded protein forms a heterodimer with PSD-95 that may interact at postsynaptic sites to form a multimeric scaffold for the clustering of receptors, ion channels, and associated signaling proteins (1, 2).

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。

关于电泳缓冲液,奇怪又好笑的问题蛋白质和糖学技术讨论版...123

灬丨牛牛丨灬2021-07-31

笔者小白，做WB时发现了一个奇怪的问题：

电泳缓冲液购买Solarbio的成品（5X），后稀释成1X工作液。

电泳条件：80V120V（注：内外槽每次用的都是新配液体，未使用回收后液体，且泳槽无漏液现象）

电流仪器：Bio-Rad

奇怪的事情在于：当我设定恒定电压为80V跑的时候，查看电流显示为35mA，且电流数值随着时间变化不断降低，半小时后约降至23mA。

请教大神们，之前有没有遇到这样的问题？这倒底是什么原因造成的，应该如何改善？

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。

DNA分子在高于其等电点的pH溶液中中带负电,因为所说的等电点是指蛋白质或两性电解质所带净电荷为零时溶液的pH,此时蛋白质或两性电解质在电场中的迁移率为零.当外界溶液的pH大于两性离子的等电点值,两性离子释放质子带负电；当外界溶液的pH小于两。

电泳缓冲液的配制 123

生物之王2017-10-02

1.配0.5M的pH8.0的EDTA时不知道酸度计准不准，反正配100mL加了2g多一点NaOH，显示差不多pH8.0,最后搅拌后都溶解了,pH调的比较粗放不知道对用于配TAE有没有影响
2.配好的EDTA不灭菌行不?放4度冰箱等过完年回来直接拿去配TAE
3.TAE配好后不用灭菌吧

我们实验室用的是：5*SDS-PAGE电泳缓冲液0.125Mtris15.1g,1.25Mglycine94g,0.5%SDS5.0g,加入800ml去离子水，搅拌溶解。加去离子水将溶液定容至1L后，室温保存。用的时候稀释成1*的就可以了。转膜缓冲液的配制方法：39mMglycine2.9g,。

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

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

保存得当，确保缓冲液没受污染，没长毛的话，就可以用。
但是最好还是不要用，影响实验就不好了。
