Biological Description

Alternative Names	lysine Antibody, acetyl lysine Antibody
Research Areas	Acetylation, Cell Signaling, Post-translational Modifications
Scientific Background	Post-translational modifications of proteins play critical roles in the regulation and function of many known biological processes. Proteins can be post-translationally modified in many different ways, and a common post-transcriptional modification of Lysine involves acetylation (1). The conserved amino-terminal domains of the four core histones (H2A, H2B, H3 and H4) contain lysines that are acetylated by histone acetyltransferases (HATs) and deacetylated by histone deacetylases (HDACs) (2). Protein posttranslational reversible lysine Nε-acetylation and deacetylation have been recognized as an emerging intracellular signaling mechanism that plays critical roles in regulating gene transcription, cell-cycle progression, apoptosis, DNA repair, and cytoskeletal organization (3). The regulation of protein acetylation status is impaired in the pathologies of cancer and polyglutamine diseases (4), and HDACs have become promising targets for anti-cancer drugs currently in development (5).

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。

北京COOLABER隆重推出PBS、TAE、TBE、蛋白电泳缓冲液独立包装预混干粉试剂，配缓冲液像冲咖啡一样简单，您只需要准备容器和水，就一切OK啦！什么计算配比，什么称重，什么调PH值，都去他的！联系电话：010-8244451715132878855400-878-6800QQ:1002073414李云云

电泳时,缓冲液为弱酸性或中性,DNA为什么会带负电?123

猴琢型182017-10-02

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小于两性离子的等电点值,两性离子质子化带正电.

【求助】跑SDSPAGE的电泳缓冲液需要什么水来配制经验共享 ...123

小聪用的03832017-10-02

跑SDS-PAGE的电泳缓冲液需要什么水来配制，我以前都用一馏水配制，但是有时配制好的电泳缓冲液比较混倒入电泳槽中，都看不清楚琼脂糖封底的下面有没有气泡。最近实验室有人用给细胞配液用的二馏水配制缓冲液，很清澈，跑的电流电压好像也没受什么影响啊，不是说电泳时需要有离子的吗，二馏水里基本是什么都没有了啊。另外，电泳时电流与什么有关，我跑电泳时同样的电压但是电流都不相同，而且现在电流没有以前大了电泳时间也延长很多

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？
