MCC950产品问题解答
请问 MCC950 sodium 和 MCC950 有什么区别?
MCC950 sodium是 MCC950 的钠盐形式,活性与使用方法都与 MCC950 一致,并且 MCC950 sodium 具有更好的溶解性,更适合实验使用。
常见问题解答
是否能直接用缓冲液对抑制剂 DMSO 母液做梯度稀释?
大部分情况下,都是可以溶解的。但有时,有机试剂直接加入水相介质时会析出。建议将抑制剂先以DMSO做梯度稀释,再将经过稀释的抑制剂加入缓冲液或细胞培养基。有些抑制剂甚至只有在其工作浓度下才能溶于水相。 比如细胞实验中希望终浓度为 1 μM 的话,可以把 10 mM 的 DMSO 母液用 DMSO 稀释到 1 mM,再吸 2 μL 加入到 2 mL 的生理盐水/PBS/细胞培液,终浓度即为 1 μM。 为避免药物析出,稀释前,可将母液和培养基 37℃ 预热,避免温度低造成严重析出。若稀释过程中出现化合物析出的情况,建议您采用超声加热的方法使其复溶。
购买多次产品,发现颜色不同,怎么办?
首先请您确认批次,如果是同一个批次产品,请联系技术同事核查产品颜色。如果是不同批次,请您放心,颜色不同可能是生产工艺不同而造成的,生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑,可在官网下载相应的质检报告,我们是对产品质量负责的。
细胞实验中需要加多少抑制剂?
通常建议您参考同模型实验发表的文献报道;除参考文献报道以外,还需要通过预实验做“剂量-效应曲线”确定最佳作用浓度(浓度梯度);通过“时间-效应曲线”确定最佳孵育时间(处理时间梯度)。另外,抑制剂的使用量受多种因素影响,包括抑制对象的可接触性、细胞通透性、孵育时间、细胞种类等等。我们建议通过检索文献确定使用抑制剂的起始浓度。 如果有报道的 Ki 值或 IC50 值,可以采用其 5-10 倍的量开始尝试以达到抑制酶活性的最佳效果。 如果抑制剂的 Ki 值或 IC50 值未知,则需要在更广泛的范围尝试抑制剂的使用浓度,并采用 Michaelis-Menten 动力学计算 Ki 值。 一般设立溶解抑制剂时所采用的溶剂作为对照,以排除溶剂的非特异性影响。
溶解度中写的“< 1 mg/mL refers to the slightly soluble or insoluble ”是什么意思?
这句话指的是,如果溶解度 < 1 mg/mL,那我们就认为它是微溶或不溶的,这是针对写的“DMSO:Insoluble”或“DMSO:slightly soluble”这类化合物的。
母液配置的计算方法?
(1) c=n/v=m/M/v 浓度=物质的量/体积=质量/相对分子质量/体积 (2) 官网产品详情页下方有溶液配制表格,可以参考计算好的加入溶剂体积

产品介绍

生物活性
产品描述
CP-456773 (MCC950 (CP-456773) and CRID3) is an effective and specific cytokine release inhibitor and NLRP3 inflammasome inhibitor. CP-456773 inhibits IL-1β secretion and caspase 1 processing. MCC950 blocked canonical and noncanonical NLRP3 activation at nanomolar concentrations. MCC950 specifically inhibited activation of NLRP3 but not the AIM2, NLRC4 or NLRP1 inflammasomes. MCC950 reduced IL-1β production in vivo and attenuated the severity of experimental autoimmune encephalomyelitis (EAE), a disease model of multiple sclerosis.
靶点活性
HMDM:8.1 nM, BMDM:7.5 nM
体外活性
MCC950以纳摩尔浓度阻断NLRP3的典型与非典型激活,特异性地抑制NLRP3而不影响AIM2、NLRC4或NLRP1的激活。在小鼠骨髓来源的巨噬细胞(BMDM)和人源单核细胞衍生的巨噬细胞(HMDM)中测试了MCC950对NLRP3炎症体激活的影响,BMDM中MCC950的半抑制浓度(IC50)约为7.5 nM,而在HMDM中具有相似的抑制能力(IC50=8.1 nM)。MCC950还呈剂量依赖性地抑制IL-1β的分泌,但不抑制TNF-α的分泌。在非典型途径激活下,MCC950特异性阻断由caspase-11直接引起的NLRP3激活和IL-1β的分泌。即使在10 μM的浓度下,MCC950也不抑制由沙门氏菌(Salmonella typhimurium)激活的NLRC4刺激的IL-1β和TNF-α的分泌。在响应S. typhimurium时,MCC950不抑制caspase-1的激活或IL-1β的处理。MCC950处理对细胞裂解物中的pro-caspase-1和pro-IL-1β的表达没有显著影响[1]。
体内活性
MCC950通过减少白介素-1β (IL-1β) 的产生和减轻实验性自身免疫性脑炎症(EAE) 的严重程度,来延缓多发性硬化症模型的发展。MCC950预处理能降低IL-1β和IL-6的血清浓度,但对TNF-α的数量影响不大。在小鼠身上应用MCC950能延缓EAE的发病时间并减轻症状。通过对第22天牺牲小鼠的脑部单核细胞进行细胞内细胞因子染色和流式细胞术(FACS)分析显示,与PBS处理的小鼠相比,MCC950处理的小鼠中IL-17和IFN-γ产生的CD3+ T细胞的频率有轻微降低。具体来说,IFN-γ和特别是IL-17产生的细胞数量在CD3+ T细胞的CD4+和γδ+亚群中也有所减少。
激酶实验
Disk diffusion is conducted, except that 10 μg of each antibiotic compound is used per filter. Growth in liquid medium in the presence of CHIR-090 is evaluated as follows: cells from overnight cultures are inoculated into 50 mL portions of LB broth at an A600 of 0.02 and grown with shaking at 30°C. When the A600 reaches 0.15, parallel cultures are treated with either 6 μL of 500 μg/mL CHIR-090 in DMSO or 6 μL of DMSO. To assess cumulative growth, cultures are maintained in log phase growth by 10-fold dilution into pre-warmed medium, containing the same concentrations of DMSO or DMSO/CHIR-090, whenever the A600 reaches 0.4. The minimal inhibitory concentration is defined as the lowest antibiotic concentration at which no measurable bacterial growth is observed in LB medium containing 1% DMSO (v/v), when inoculated at a starting density of A600=0.01. Cultures are incubated with shaking for 24 h at 30°C in the presence of CHIR-090. Experiments are performed in triplicate[1].
细胞实验
MCC950 is dissolved in DMSO and stored, and then diluted with appropriate media before use[1]. BMDM are seeded at 5×105/mL or 1×106/mL, HMDM at 5×105/mL and PBMC at 2×106/mL or 5×106/mL in 96 well plates. The following day the overnight medium is replaced and cells are stimulated with 10 ng/mL LPS from Escherichia coli serotype EH100 (ra) TLRgrad for 3 h. Medium is removed and replaced with serum free medium (SFM) containing DMSO (1:1,000), MCC950 (0.001-10 μM), glyburide (200 μM), Parthenolide (10 μM) or Bayer cysteinyl leukotriene receptor antagonist 1-(5-carboxy-2{3-[4-(3-cyclohexylpropoxy)phenyl]propoxy}benzoyl)piperidine-4-carboxylic acid (40 μM) for 30 min. Cells are then stimulated with inflammasome activators: 5 mM adenosine 5'-triphosphate disodium salt hydrate (ATP) (1 h), 1 μg/mL Poly(deoxyadenylic-thymidylic) acid sodium salt (Poly dA:dT) transfected with Lipofectamine 200 (3-4 h), 200 μg/mL MSU (overnight) and 10 μM nigericin (1 h) or S. typhimurium UK-1 strain. Cells are also stimulated with 25 μg/mL Polyadenylic-polyuridylic acid (4 h). For non-canonical inflammasome activation cells are primed with 100 ng/mL Pam3CSK4 for 4 h, medium is removed and replaced with SFM containing DMSO or MCC950 and 2 μg/mL LPS is transfected using 0.25% FuGENE for 16 h. Supernatants are removed and analysed using ELISA kits. LDH release is measured using the CytoTox96 non-radioactive cytotoxicity assay[1].
