Ki: 7.8 and 7,9 nM for CB1 and peripheral cannabinoid (CB2), respectively
(S)-SLV 319 is a CB1 receptor antagonist.
It has been reported that central cannabinoid (CB1) receptor antagonists may have potential in the treatment of a variety of diseases including cognitive disorders, neuro-inflammatory disorders, obesity, septic shock, psychosis, addiction, as well as gastrointestinal disorders.
In vitro: Previous study found that (S)-SLV 319 was a potent and selective CB1 receptor antagonist with Ki values of 7.8 and 7,9 nM for CB1 and CB2, respectively. In addition, (S)-SLV 319 was found to be less lipophilic and thus more water soluble than other previously identifiedligands of CB1 receptor [1].
In vivo: Previous animal study showed that in rats exposed to an ambient temperature of 22°c, a moderate dose of LPS at 25 - 100 μg/kg could induce a fall in body temperature. Such response was not affected by desensitization of intra-abdominal TRPV1 receptors with resiniferatoxin at 20 μg/kg, by systemic TRPV1 antagonism with capsazepine at 40 mg/kg, or by systemic CB2 receptor antagonism with SR144528 at 1.4 mg/kg. In contrast, CB1 receptor antagonism by SLV319 at 15 mg/kg or rimonabant at 4.6 mg/kg was able to block LPS caused hypothermia [2].
Clinical trial: So far, no clinical study has been conducted.

质粒转染一般是说DNA转染,用常用的sinofection等转染试剂就可以;
小干扰RNA(Small interfering RNA;siRNA)有时称为短干扰RNA(short interfering RNA)或沉默RNA(silencing RNA),是一个长20到25个核苷酸的双股RNA,这种RNA的转染需要用专门的RNA转染试剂。
如题,PolyplusTransfection转染试剂在中国区的代理商有哪些?求推荐1-2个靠谱的,谢谢!
想用RNAiMAX或者lipo2000转染siRNA,但是看了下转染试剂的说明书和锐博的siRNA说明书,觉得分别对siRNA的用量描述差别挺大的呀,不知道到底该参考哪个呢。
以24孔板为例在siRNA说明书中写到,siRNA终浓度是50nM的话,加入浓度为20μM的siRNA1.25ul,每孔体积是500ul,那这样的话,每孔最终siRNA的量是25pmol。
但是在RNAiMAX或者是lipo2000说明书中,一个写的每孔siRNA用量是5pmol,一个是500ng,这与siRNA厂家所提供的量相差也太多了吧。
到底该看哪一个呢。
ps.一旦siRNA的量和体积确定下来之后,转染试剂的量和siRNA1:1的加就可以了吗?
请各位大神解答。
1.siRNA说明书中的用量,红线圈出
2.RNAIMAX说明书中siRNA的用量。
3.lipo2000说明书中siRNA用量
对重复性要求不高的试验,一般没有问题的,只不过可能需要增加一些转染试剂用量了。
为了避免这个问题,推荐收到货之后,进行适当分装,用多少,拿出来多少最好。
但是在选择的时候,也需要注意其他的一些问题。
1、采用何种原料和抗体,是否高效、灵敏、特异
2、规范包被操作,吸附是否均匀
3、重复性、可靠性
6、是否提供技术服务
7、适用于血浆、血清、组织匀浆液、细胞培养上清液、尿液等多种类型的样本
8、可检测动物类型是否丰富
9、可检测指标是否齐全

使用方法:
1、 血清:操作过程中避免任何细胞刺激。使用不含热原和内毒素的试管。收集血液后,1000×g离心10分钟将血红细胞迅速小心地分离。
2、 血浆:EDTA、柠檬酸盐、肝素血浆可用于检测。1000×g离心30分钟去除颗粒。
3、 细胞上清液:1000×g离心10分钟去除颗粒和聚合物。
4、 组织匀浆:将组织加入适量生理盐水捣碎。1000×g离心10分钟,取上清液。
5、 保存:如果样品不立即使用,应将其分成小部分-70℃保存,避免反复冷冻。尽可能的不要使用溶血或高血脂血。如果血清中大量颗粒,检测前先离心或过滤。不要在37℃或更高的温度加热解冻。应在室温下解冻并确保样品均匀地充分解冻。
内毒素是革兰氏阴性菌细胞壁(cellwall)上的特有成分,主要是脂多糖中的类脂A,在细菌被裂解时被释放出来,由于其化学结构和特性,在质粒的纯化过程中很容易混入质粒DNA一同提取出来。内毒素的存在会严重的影响质粒转染细胞的效率,此外会激活造血细胞(如B细胞、巨噬细胞等)的非特异免疫反应,造成实验的假阳性,所以转染级质粒的提取纯化必须去除内毒素。
