Galanin is a 29-aa neuropeptide with a complex role in pain processing. Galanin receptor subtypes are present in dorsal root ganglia and spinal cord with a differential distribution. Three galanin receptors, GalR1, GalR2 and GalR3, have been identified and cloned. AR-M1896 is a specific galanin R2 (GalR2) agonist.
In vitro: Additional removal of the glycine residue in position 1 resulted in AR-M1896 with almost unchanged GalR2 affinity and functional activity, and 500-fold selectivity for GalR2-Rs over GalR1-Rs. This compound represents a truly GalR2-selective galanin analog and, thus, could be used as a pharmacological tool to differentiate between these two receptors [1].
In vivo: In normal rats mechanical and cold allodynia of the hindpaw are induced by intrathecal infusion of low-dose galanin. The same effect is seen with equimolar doses of AR-M1896 or AR-M961 (an agonist both at GalR1 and GalR2 receptors). In allodynic Bennett model rats, the mechanical threshold dose-dependently increased after intrathecal injection of a high AR-M961dose, whereas no effect was observed in the control or AR-M1896 group. No effect of either compounds was observed in nonallodynic Bennett model rats [1].
Clinical trial: Up to now, AR-M1896 is still in the preclinical development stage.

利用NheI和HindIII双酶切插入目的片段，为什么双酶切有目的片段和切开的质粒，测序却没有？
并且测序后在NheI位点后的序列变成了-GGCTAGGTAC-Kpn位点（CGTTTAAACTTAAGCTTG消失。之前和之后的序列都相符），之间的怎么都没了？
请教高人，这样的问题怎么解决？
多谢
你所说的“测序酶”在一般情况下就是“聚合酶”。
因为目前的的测序方法主要就是借助聚合反应。
当然，有些测序方法（比如曾经的SOLiD系统）是利用连接反应，那么它用的“测序酶”肯定是连接酶。
估计，也就是这个原因有人把它。
两个基因大小分别230kb和450kb，酶切后，450kb的有目的条带，但很弱，230kb的质粒条带亮，其下方有一很微弱条带，用的酶分别是：Ncol和Spel体系是（Takara，两个酶切体系不同，用的官网推荐体系）：
NcoI1μl
Spel1μl
10×KBuffer2μl
0.1%BSA2μl
DNA3ul
灭菌水upto20μl37℃4h电泳1h
期待着高手们的指点，谢谢。
【之前构建的4个重组质粒里也有两个出现这样的问题（aagtcc变成agtcc），但是酶切能切出插入的片段】
目前问测序公司得到的答复是样品可能不是单克隆，测序结果是不准确的，建议重新挑取单克隆测序。
不知道还有没有别的方法？
