产品详情	Galantide 是一种特殊的甘丙肽受体 (galanin receptor) 拮抗剂，是一种由甘丙肽和 P 物质片段组成的肽段，在大鼠下丘脑可识别两类甘丙肽结合位点 (K_D 分别小于 0.1 nM 和 ~6 nM)。Galantide 剂量依赖性 (IC₅₀=1.0 nM) 拮抗甘丙肽介导的葡萄糖诱导的小鼠胰岛胰岛素分泌抑制。Galantide 似乎与单一的 SP 受体群结合 (K_D~40 nM)。
生物活性	Galantide, a non-specific galanin receptor antagonist, is a peptide consisting of fragments of galanin and substance P. Galantide recognizes two classes of galanin binding sites (K D <0.1 nM and ~6 nM) in the rat hypothalamus. Galantide dose dependently (IC 50 =1.0 nM) antagonizes the galanin-mediated inhibition of the glucose-induced insulin secretion from mouse pancreatic islets. Galantide appears to bind to a single population of SP receptors (K D ~40 nM).
性状	Solid
体外研究(In Vitro)	Galantide do not activate the K conductance but produces a concentration-dependent antagonism (IC50=4 nM) of the galanin-induced increase in K conductance. Galantide acts like galanin and inhibits the voltage-dependent Ba2+ current (IBa). The inhibition of IBa also is concentration dependent (IC50=16 nM) and the maximum inhibition produced by galantide is approximately 40%. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)	Intracerebroventricular injection of galanin (5 micrograms/rat) inhibited sexual behavior in experienced male rats--without producing any other locomotor or behavioral deficit-, injection of the galanin antagonist, galantide, by the same route (1 or 2 micrograms/rat) stimulated sexual behavior (improving arousal, motivation and performance indexes) and antagonized the effect of galanin. Galantide ameliorates mild acute pancreatitis (AP). Galantide significantly reduces AP-induced hyperenzymemia by 41–49%. Galantide has been found to improve social memory in socialrecognition test when i.c.v. administered at doses varying from 6-6000 nM. has not independently confirmed the accuracy of these methods. They are for reference only.

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
