(±)-Myristoylcarnitine chloride is an agonist for cholinergic and a homolog of acetylcarnitine chloride (Cat No. B6273).
Acetylcholine receptor (AChR) is an integral membrane protein receptor for acetylcholine. There are two kinds of AChRs: nicotinic acetylcholine receptors and muscarinic acetylcholine receptors.
(±)-Myristoylcarnitine chloride is a cholinergic agonist and an intermediate in lipid metabolism [1]. In retinal ganglion cells, acetylcarnitine and acetylcholine inhibited GABAergic responses to exogenous GABA and GABAergic inhibitory postsynaptic currents [2].
In dogs with coronary ligation, (-)-carnitine chloride (LCC) (300 mg/kg) and acetyl (-)-carnitine chloride (ALCC) (300 mg/kg) inhibited the ventricular arrhythmia. Also, LCC and ALCC improved oxidative phosphorylation rate and the mitochondrial function [1]. In the mouse hot plate test, acetyl-l-carnitine (ALCAR) (100 mg/kg) exhibited analgesia. While, U-73122 and neomycin (the phospholipase C (PLC) inhibitors) blocked the increase of the pain threshold induced by ALCAR. LiCl that impairing phosphatidylinositol synthesis antagonized the antinociception in a dose-dependent way. PMA and PDBu (PKC activators) blocked the increase of the pain threshold in a dose-dependent way. These results suggested that ALCAR analgesia required the participation of the PLC-IP3 pathway [3].

然后往容器中滴液体直至读数为0.70时就可以了
我们每天长时间都在实验室里和移液器（俗称“枪”）打交道，枪已经成为实验室标配，因为它是很多实验过程和分析的基础。但正因为如此，我们都认为它很简单，就像走路和呼吸一样自然，不需要你花任何心思，它就可以做你想做的事情。但事实真的是这样吗？
事实上，枪虽小但往往关系到实验结果的准确性，有小伙伴经常抱怨枪老出问题：
1.用了一段时间就不准漏液了？
2.液体容易倒吸？
3.移液排不干净？……
到底是哪里出问题了呢，你有没有碰到这样的迷之困惑？
当当当，福利到，来自梅特勒-托利多瑞宁移液技术专家自告奋勇来解答大伙儿的困惑，有任何关于移液器使用的问题欢迎来和我们探讨共同进步哟~
最后感谢丁香园支持本活动！
我们会每天抽时间统一回复大家的问题，专家答疑截止12月31日哦！
塑料类工具灭菌有什么需要注意的吗？谢谢！
2、吸液：用右手的拇指和中指捏住移液管的上端，将管的下口插入欲吸取的溶液中，插入
不要太浅或太深，一般为10～20mm处，太浅会产生吸空，把溶液吸到洗耳球内弄脏溶液，
太深又会在管外沾附溶液过多。左手拿洗耳球，接在管的上口把溶液慢慢吸入，先吸入该管 容量的1/3
左右，用右手的食指按住管口，取出，横持，并转动管子使溶液接触到刻度以上 部位，以置换内壁的水分，然后将溶液从管的下口放出并弃去，如此用反复洗3
次后，即可 吸取溶液至刻度以上，立即用右手的食指按住管口。 3、调节液面：将移液管向上提升离开液面，管的末端仍靠在盛溶液器皿的内壁上，管身保
持直立，略为放松食指（有时可微微转动吸管）使管内溶液慢慢从下口流出，直至溶液的弯
月面底部与标线相切为止，立即用食指压紧管口。将尖端的液滴靠壁去掉，移出移液管，插 入承接溶液的器皿中。
4、放出溶液：承接溶液的器皿如是锥形瓶，应使锥形瓶倾斜30°，移液管直立，管下端紧
靠锥形瓶内壁，稍松开食指，让溶液沿瓶壁慢慢流下，流完后管尖端接触瓶内壁约15 秒后，
再将移液管移去，残留在管末端的少量溶液，不可用外力强使其流出，因较准时已考虑了末 端保留的溶液的体积。
大家做溶出曲线稀释溶液时有某有再用移液枪？移液枪量取1ml的体积准确不？
