Scientific Background	UNC-51 like kinase 1 (ULK1) is widely expresed and contains an amino-terminal kinase domain followed by a central proline-serine rich domain and a highly conserved carboxy-terminal domain. It has been linked to axon growth and is essential for autophagy. Structurally, ULK1 is similar to ATG1, and it appears that both Atg1/ULK1 can bind to several ATG proteins regulating phosphorylation states and protein trafficking.

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

本人对电泳了解不多，现在有个问题向大家求教；我做的是人血清脂蛋白琼脂糖凝胶电泳，我看文献上基本上是写的是用Tris-巴比妥缓冲液，但现在巴比妥和巴比妥钠很贵，用量很大，而且还买不到！我想问下可不可用其他什么缓冲液代替一下？请帮忙，谢谢大家了

【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

第二向sdspage,电泳缓冲液可以多次使用吗? 生物科学 ...123

在《分子克隆》上看见检测微量的DNA可以使用先电泳，再用含EB的电泳缓冲液染色30至45分钟。
我使用的是1%琼脂糖凝胶，电泳缓冲液为0.5×TBE。
请问各位大虾，在不影响实验结果的前提下，这样的含EB的电泳缓冲液可以反复使用多少次？

谢谢^_^

SDSPAGE电泳缓冲液的上槽液与下槽液有何区别? 123

轩子TA01942017-10-02

1。阳极缓冲液 ( 10 × ) ：121.14g Tris 溶于400ml 蒸馏水，用 1.0mol/L HCl 调至 pH8.9 ,定容至
500ml
2。阴极缓冲液 ( 10 × ) ：将 60.55g Tris ,89.58g Tricine 及 5g SDS 溶于400ml 蒸馏水中，加水至终体积为500ml
使用时稀释至1×的缓冲液，电泳槽内槽加入阴极电泳缓冲液，外槽加入阳极电泳缓冲液。形成Trcine-SDS-PAGE电泳系统。

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

zcxy43162021-07-24

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！
