Oleoyl Serotonin is a TRPV1 antagonist with IC50 value of 2.57 μM for human TRPV1 [1].
The transient receptor potential vanilloid-type 1 (TRPV1) channel is a nonselective cation channel that may be activated by a variety of exogenous and endogenous physical and chemical stimuli. TRPV1 is decreased in the injured nerve fibers but increased in those proximal to the site damage. TRPV1 is a potential new target for the development of analgesic and anti-inflammatory drugs [1].
Oleoyl serotonin is a hybrid molecule patterned after arachidonoyl serotonin. Arachidonoyl serotonin is a dual antagonist of TRPV1 and fatty acid amide hydrolase (FAAH) with IC50 values of 0.27 and 8 μM, respectively. Arachidonoyl serotonin was highly effective against both acute and chronic peripheral pain [1][2]. In TRPV1 and FAAH assays, Oleoyl serotonin inhibited anandamide hydrolysis by FAAH and capsaicin-induced intracellular Ca2+ elevation in HEK293 cells overexpressing the human recombinant TRPV1 receptor with IC50 values of > 50 μM and 2.57 μM, respectively [1].

参考见解:只是固定方法不同。细胞固定用甲醇,切片固定用多聚甲醛,而染色方法是一样的。
2、问:近期要做免疫荧光双标,不知哪位有免疫荧光双标技术的详细步骤及其注意事项?
参考见解:我正在做冰冻组织切片的免疫荧光双染。我的经验是:
(1)选取一抗时要来源于两种不同的动物,我用的是来源于rabbit和rat的抗体,二抗则是不同荧光信号标记的,我用的是donkey anti-rabbit-FITC(绿)和donkey anti-rat-Tex-Red(红)。
(2)我的做法是两种一抗(CHI抗体)同时孵育,然后两种二抗同时孵育。抗体浓度、孵育时间要仔细摸索,我感觉一抗4度孵育过夜比较好,背景比较清晰。
(3)我的阳性对照用的是阳性组织切片,阴性对照则分别是家兔和大鼠的IgG,荧光标记物对照是PBS+荧光标记物。
(4)封闭血清与二抗来源动物一致,我用的是10%的正常donkey血清。
(5)其余步骤同一般免疫荧光单标操作。
3、问:本人拟做Brdu标记神经干细胞免疫荧光,二抗为FITC标记,想请教各位大侠:
(1)抗体分装和荧光显微镜观察时是否一定要在暗室中进行?
(2)封片时是否用甘油缓冲液即可,还是用甘油和0.5mmol/L pH9.0-9.5的碳酸氢盐缓冲液等量混合封片?
(3)免疫酶染色中的3%过氧化氢及2N盐酸是否还需要用?
参考见解:
(1)你的二抗是用FITC标记的,为避免荧光分解,分装及荧光显微镜观察时均要避光;
(2)封片最好用甘油加0.5mmol/L pH9.0-9.5的碳酸氢盐缓冲液,后者能使玻片透明;
(3)关于免疫酶染色,如果是用过氧化物酶做标记,就必须用3%H2O2以去除内源性过氧化物酶;2N盐酸需要使用,目的是使DNA变性,让Brdu抗体能够充分地与已经掺入的Brdu结合。
4、问:做间接法免疫荧光染色,如何设置对照?
参考见解:最好是同一视野在未用荧光激发下进行对照,看是否非特异性染色。
(1)空白对照:如果你做的是石蜡切片免疫组化,这个对照必须有,目的是看自发荧光,脱蜡后直接在荧光显微镜下观察。
(2)阴性对照:标本直接滴加二抗,呈阴性反应。
(3)抗原对照:标本加同种动物的未免疫血清,以PBS冲洗后,在加抗免疫球蛋白荧光抗体。因未免疫动物的血清中无特异性抗体,应呈阴性反应。
5、问:我做乳腺组织的免疫荧光染色,结果用激光共聚焦显微镜看很好:有阳性信号,阴性对照组也没有荧光,但是拿到荧光显微镜下看,我的阴性对照组一片绿,像非特异性染色,到底哪个结果才是真实的呢?
参考见解:激光共聚焦显微镜的分辨率比普通荧光显微镜要高的多,出现上述现象首先要排除荧光显微镜的问题,如是不是紫外灯泡寿命到期了或者别的原因,荧光显微镜没有问题,那就以共聚焦显微镜的结果为主。展开
2.-20度甲醇固定20分钟后,自然、干燥 10分钟
3.PBS洗净:3min*3
4.1%Triton:25min-30min.配成50ultriton+5mlpBS
5.PBS洗净:2*5min
6.羊血清封闭:37度,20分钟
7.一抗,4度过夜,一般要大于18小时或者37度 1-2小时
8.4度 PBS洗净,3min*5次
9.二抗 37度小于一小时
,我需要这个仪器有关的供应商的信息,有知道的人不,腾讯看你的专家团队给力不,想买这个仪器,但关于这个资料我已经了解很多了,但不知道去哪引进,哪里买。麻烦告诉哪里买,
血清封闭:组织切片上有剩余的位点可以与一抗非特异性结合,造成后续结果的假阳性;封闭血清一般是和二抗同一来源的,血清中动物自身的抗体,预先能和组织中有交叉反应的位点发生结合;也可以用小牛血清、BSA、羊血清等,但不能与一抗来源一致。
针对这个应该有详细的解说的
