Product Introduction
Bioactivity
| 名称 | ZCL278 |
| 描述 | ZCL278 is a selective Cdc42 GTPase inhibitor. |
| 细胞实验 | ZCL278 is prepared in DMSO and stored, and then diluted with appropriate medium before use[1]. To determine cell viability, PC-3 cells are incubated for 24 h with or without the Cdc42 activator, ZCL278, or NSC23766. By using the trypan blue dye exclusion method, the numbers of live and dead cells are obtained with a Countess Automated Cell Counter. P values are assigned in each experiment, and any null hypothesis with probability level <95% is rejected[1]. |
| 激酶实验 | Lyophilized Cdc42 protein is reconstituted to 5 mg/mL in a buffer consisting of 50 mM Tris, 0.5 mM MgCl2, 50 mM NaCl, 3% (wt/vol) sucrose, and 0.6% dextran. The stock solution is then diluted to 1 μM in 5 mM phosphate buffer, pH 7.4. Into a quartz cuvettete containing Cdc42 solution, aliquots of ZCL278 are added and incubated for 5 min before each fluorescent measurement. The excitation wavelength is 275 nm, and the fluorescence of tryptophan at 350 nm is measured after each addition. The titration curve is fitted using the equimolar specific binding model in GraphPad, and the Kd is calculated[1]. |
| 体内活性 | ZCL278在脾脏中将JUNV RNA负荷降低了33倍以上,其中5只小鼠中JUNV RNA无法检测到。这些结果与Gabapentin处理的小鼠相似,表明ZCL278能够有效抑制JUNV的复制[2]。 |
| 存储条件 | Powder: -20°C for 3 years | In solvent: -80°C for 1 year Shipping with blue ice/Shipping at ambient temperature. |
| 溶解度 | 10% DMSO+40% PEG300+5% Tween 80+45% Saline : 10 mg/mL (17.1 mM), Solution. DMSO : 125 mg/mL (213.72 mM), Sonication is recommended. 10% DMSO+90% Saline : < 10 mg/mL (17.1 mM), Lower concentrations may be soluble, but exact solubility limit is unknown. |

文献和实验处理降低了Cdc42的热稳定性,提示DA能够在细胞内与Cdc42发生相互作用(图4A)。 为了定量评价DA与Cdc42之间的直接结合,作者进一步采用表面等离子体共振技术(SPR)测定二者的结合亲和力,并以已知Cdc42结合化合物ZCL278作为阳性对照。SPR结果显示,DA与Cdc42的解离常数(KD)为15.6 μM,ZCL278与Cdc42的KD为18.6 μM,表明DA能够与Cdc42直接结合(图4B)。 随后,作者采用分子对接预测DA与Cdc42的潜在结合模式。结果显示,DA可能与Cdc
在遗传工程细胞(细菌,酵母或哺乳动物细胞)中,会针对被分析物质反应产生BL信号。在细胞中引入报告基因融合到一个调控DNA序列后,并在被分析物存在的情况下被激活及紧密调控,如图Figure 1a所示。基于细胞的检测方法的一个重要特性是其可以经得起自动化高通量筛选的检验。 目前已有多种BL全细胞生物传感器用来进行环境监测(如表2)。它们可以检测多种普通的胁迫条件,有毒物质,氧化剂,金属和组织寄生物[47],和一些可以激活报告基因的分子(例如,内分泌活性物质或者多卤化芳香碳氢化合物)[48] 或其他细胞
乙醇提取胰岛素,既可抑制水解酶对胰岛素的破坏,又可除去大量杂蛋白,用丁醇提取某些附于微粒体和线粒体的酶,一些与脂质结合牢固的蛋白质和酶以丁醇提取,效果较好。我国生化工作者曾用此法成功地提取了琥珀酸脱氢酶和碱性磷酸脂酶。丁醇提取法对pH及温度的选择范围较广(Ph3~10),温度由零下2℃~40℃均可。 2.核酸的提取 核酸分为两大类:一类为核糖核酸(RNA),另一类为脱氧核糖核酸(DND)。核酸的分子量极大,人数万致亿万。核酸是两性化合物,在一定的等电点。溶于水,其水溶液呈酸性,不溶于乙醇
