- MolecularFormula:
- C20H23N2NaO5S
- Purity:
- >98%
- Target:
- NOD-like Receptor (NLR)
- IC50:
- IC50: 7.5 nM (NLRP3, in BMDMs), 8.1 nM (NLRP3, in HMDMs)[1]
- In Vitro:
- MCC950 blocks canonical and non-canonical NLRP3 activation at nanomolar concentrations. MCC950 specifically inhibits NLRP3 but not AIM2, NLRC4 or NLRP1 activation. The effect of MCC950 on NLRP3 inflammasome activation is tested in mouse bone marrow derived macrophages (BMDM) and human monocyte derived macrophages (HMDM). The IC50 of MCC950 in BMDM is approximately 7.5 nM, while in HMDM it has a similar inhibitory capacity (IC50=8.1 nM). MCC950 also dose dependently inhibit IL-1β but not TNF-α secretion.MCC950 specifically blocks caspase-11-directed NLRP3 activation and IL-1β secretion upon stimulation of the non-canonical pathway. NLRC4-stimulated IL-1β and TNF-α secretion (as activated by Salmonella typhimurium) are not inhibited by MCC950 even at a concentration of 10 µM. MCC950 does not inhibit caspase-1 activation or IL-1β processing in response to S. typhimurium. The expression of pro-caspase-1 and pro-IL-1β in cell lysates is not substantially affected by MCC950 treatment[1].
- In Vivo:
- MCC950 reduces Interleukin-1p (IL-1β) production and attenuates the severity of experimental autoimmune encephalomyelitis (EAE), a disease model of multiple sclerosis. Pre-treatment with MCC950 reduces serum concentrations of IL-1β and IL-6 while it does not considerably decrease the amount of TNF-α. Treatment of mice with MCC950 delays the onset and reduced the severity of EAE. Intracellular cytokine staining and FACS analysis of brain mononuclear cells from mice sacrificed on day 22 shows modestly reduced frequencies of IL-17 and IFN-γ producing CD3+ T cells in MCC950 treated mice in comparison with PBS-treated mice. IFN-γ and particularly IL-17 producing cell numbers are also reduced in both the CD4+ and γδ+ sub-populations of CD3+ T cells[1].

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
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
今天文章就简单整理了一下最近遇到的问题,有些问题对你来说可能很简单,但是还是会给一些科研菜鸟带去小麻烦,特整理了这么个专场来涨涨姿势。
这里就简单整理了5个问题,具体内容如下:
小编自己在各大论坛看到最多的三个答案:
1)48T可做42个样本加6个标准曲线;96T可做90个样本加6个标准曲线
2)以96T试剂盒来算,定量的试剂盒一般可以做90个左右的样品,定性的试剂盒可以做94个左右的样品
3)96T的ELISA试剂盒,去除标准品复孔检测,最多还能检测80个标本;48T的最多30个样本。
2、elisa试剂盒96T的能做检测多少血清样品?板能重复利用吗?
96T,一般做复孔的话,做标准曲线需要16个孔,剩下80个孔就可以做40个样本。这个板不能重复利用。而且配套的试剂也只是够一块板子用的。
3、想请教一下,我想用elisa法测血清里的一种抗原,查了资料,发现没有现成的试剂盒用,现在就有2种备选方案,一种是买抗体对自己包被(查了R&D等大公司都没有可用于elisa的单抗)。哪种比较好呢?自己包被的会不会比国产的试剂盒可靠呢?
如果你觉得技术不错有队其他公司不放心,可以自己购买抗体对自己包被,这个就是麻烦点,自己包被用着放心,舒心;
另外国内还是有一些资质不错的公司,如北京达科为,上海巧伊,依科赛,深圳欣博盛等等
4、western和ELISA处理样本有何差别?
WesternBlot样品制备要加蛋白裂解液(含有蛋白酶抑制剂),然后冰上研磨,收集于EP管,冰上裂解30min,4度12000rpm离心15min,取上清分装,即得到蛋白样品。建议直接电泳,多余的-80保存。建议分装的蛋白每支略多于一次上样量,一次性用完一支,避免反复冻融。
ELISA样品,直接脑组织冰上匀浆,收集于EP管,同上一样离心,大约220-250ul每支分装(因为ELISA上样量基本都是每孔100ul,做复孔,每个样品2孔,就需要200ul,为了避免不够2孔,分装时要大于200ul每支),直接实验。多余的-80保存,一样避免反复冻融。
不过ELISA最好少量样品进行预实验,或者查阅文献,看看大概组织里有多高浓度,选择合适的试剂盒,测量范围要与组织浓度相符。避免浓度过高测量不准,或者浓度过低,小于试剂盒最低可测浓度。
5、Elisa试剂盒该买哪家公司的呢?
提出这个问题的朋友其实该打,目前国际上各个品牌的试剂盒生厂商,都会有其偏重点,像R&D在细胞因子方面的试剂盒就非常牛逼,而其他牌子也一样的。
Bender:粘附分子方面的试剂盒;
Cayman:花生四烯酸类产品的试剂盒;
Merck(Linco):内分泌研究方面的试剂盒;
Tips:
1、买Elisa试剂盒时,尽量先查文献,通过文献找品牌,再找供应商,找供应商就找正规代理商,千万不要去干“赔夫人又折兵”的蠢事。
2、ELISA中,复孔就是同一个样品加到至少两个孔中(一般3个或4个),最后取其平均值作为样品的读数,这样测得的结果才有说服力!
做复孔是为了较好的较少组内差异,如果血清不足不做复孔也可以。
