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、

电泳缓冲液的ph为8.6时为什么会向正极移动

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？

电泳法分离蛋白质时,缓冲液的离子强度的一般要求是A.0.01～0.05B....123

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。
