体外研究 |
RG108 effectively blocks DNA methyltransferases in vitro and does not cause covalent enzyme trapping in human cell lines.Incubation of cells with low micromolar concentrations of RG108 results in significant demethylation of genomic DNA without any detectable toxicity.Intriguingly,RG108 causes demethylation and reactivation of tumor suppressor genes,but it does not affect the methylation of centromeric satellite sequences.In another study,the synthesis and in vitro analysis of a biotinylated RG108 conjugate is investigated to evaluate the interactions with DNA methyltransferase enzymes.In a recent study,it is shown RG108 can significantly reduce the DNA methyltransferases activity in SM derived iPS cells as compared to the native SMs. |

激酶实验: |
|
The substrate DNA for the in vitro methylation assay is a 798 bp fragment (−423/+375 relative to the initiation codon) from the promoter region of the human p16Ink4a gene.The methylation reaction contains 350 to 400ng substrate DNA and 4 units of M.SssI methylase (0.5μM) in a final volume of 50μL.Inhibitors are added to final concentrations of 10,100,200,and 500μM,respectively. Reactions are done at 37℃ for 2 hours.After completion,the reaction is inactivated at 65℃ for 15 minutes and the DNA is purified using PCR Purification kit.Three hundred nanograms of purified DNA is digested for 3 hours at 60℃ with 30 units of BstUI and analyzed on 2% Tris-borate EDTA agarose gels. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为:C1V1 = C2V2 ( 输入 输出 )

混匀澄清方案所需的各种助溶剂如: DMSO , PEG300 / PEG400 , Tween 80 , SBE-β-CD , 玉米油 等, 均可点击跳转或在网站搜索购买。
计算结果:
工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL Saline/PBS/ddH2O,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
