Application | In thyroparathyroidectomized Sprague-Dawley rats, (-)-p-Bromotetramisole Oxalate significantly increased fractional excretion of phosphate (FEPi) from 4.7%±0.9% to 13.4%±3.1%. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

(-)-p-Bromotetramisole Oxalate (L-(-)-p-Bromotetramisole Oxalate, L-p-Bromotetramisole Oxalate, (-)-4-Bromotetramisole Oxalate) is a potent and non-specific inhibitor of alkaline phosphatase and is also an inhibitor of protein tyrosine phosphatases [1] [2].
Alkaline phosphatase is a hydrolase enzyme that removes phosphate groups from nucleotides, proteins and alkaloids. Protein tyrosine phosphatase is an enzyme that removes phosphate groups from phosphorylated tyrosine residues on target proteins.
(-)-p-Bromotetramisole Oxalate is an inhibitor of alkaline phosphatase and protein tyrosine phosphatases. In various rat tissues, (-)-p-Bromotetramisole Oxalate (0.1 μM) completely inhibited non-specific alkaline phosphatase [1]. In rat zona glomerulosa, (-)-p-Bromotetramisole Oxalate (100 μM) blocked the inhibition of Na+ pump (Na+, K+-ATPase) induced by angiotensin II. The result suggested that inhibition of the Na+ pump induced by angiotensin II might be mediated by a tyrosine phosphatase [2]. In neurosecretory PC12 cells, (-)-p-Bromotetramisole Oxalate (0.3 mM) increased ionomycin-stimulated noradrenaline (NA) release, which suggested that tyrosine phosphorylation regulated Ca2+-stimulated NA release [3].
In Sprague-Dawley rats, (-)-p-Bromotetramisole Oxalate (10 μM) significantly increased fractional excretion of phosphate (FEPi) from 4.7% to 13.4% [4].

引物是一小段单链DNA或RNA，引物可以做为DNA复制开始时DNA聚合酶的结合位点，在细胞外的条件下，只有通过引物，DNA才可以开始进行复制。
引物是人工合成的两段寡核苷酸序列，一个引物与感兴趣区域一端的一条DNA模板链互补，另一个引物与感兴趣区域另一端的另一条DNA模板链互补。
启动子和引物两者的区别：
启动子是DNA分子上能与RNA聚合酶结合并形成转录起始复合体的区域，在许多情况下，还包括促进这一过程的调节蛋白的结合位点，决定RNA聚合酶转录起始位点的DNA序列。引物是一小段单链DNA或RNA，引物可以做为DNA复制开始时DNA聚合酶的结合位点，在细胞外的条件下，只有通过引物，DNA才可以开始进行复制。引物是人工合成的两段寡核苷酸序列，一个引物与感兴趣区域一端的一条DNA模板链互补，另一个引物与感兴趣区域另一端的另一条DNA模板链互补。
启动子是位于结构基因前的非编码区对转录起调控作用的一段DNA序列。引物则是游离于DNA复制的模板链之外的对DNA复制起调控作用的一小段单链DNA或RNA。
在这里我向大家隆重推荐一个在线的引物设计软件，是斯坦福大学的，我认为是最好的在线引物设计软件，我用它设计接近100多对引物，可以说是屡试不爽。它用起来也很简单，最重要的是效果非常好，考虑的因素也非常的多。
先不说那么多了：网址：http://www.yeastgenome.org/cgi-bin/web-primer
下面我继续图示。
帖子发表之后很多战友PM我，让我帮设计引物，其实这很让我失望的，我的本意是让大家掌握这种方法，而不是告诉大家我是一个专家，其实我水平也有限，所以我不会帮大家设计引物，我认为这是科研工作的一部分、基本功，祝大家好运、实验顺利。
帮忙设计这段DNA序列的2个引物，forwardprimer还有reverseprimer，要只含有6个bp
麻烦写详细3端和5端，可以的话写下设计方法，感激不尽啊
刚开始学很是困惑，老师也没详细讲。。。
新手一枚，看到论坛里也有许多人问过，但没找到比较确切的回答，还是不是很理解，做芯片给出的lncRNA的名字是XLOC_009167，这个名字在ncbi里面都找不出来，我该怎么样去获得这个rna的信息呢？
需要在片段5‘端和3’端分别设计引物去扩增。
所以，对应的上游5‘端，我们习惯叫做”上游引物“，即forward primer，简称for；
对应序列的3’端，我们叫做下游引物，reverse primer，简称rev。
非要说差别，可能就在测序引物是让片段线性增加，PCR引物是让片段指数增加。
请教各位高手：
1.本人最近用权威文献中的引物PCR，使用前在NCBI上BLAST了一下，可是并没有结果。这个引物可用吗？
2.自己用OLIGO7设计了一对引物，评分良好，BLAST特异性好。可是实际一直P出某条非目的条带。退火温度也按TM值调节过了。实在想不出什么原因。
3.使用NCBI上的PRIMER-BLAST设计的引物，在NCBI自己的BLAST却找不到目的片段，这是为啥？引物可用吗？
谢谢！
