体外研究 |
SKI V has weak activity toward ERK2 (IC50 of 80μM for hERK2) and does not inhibit PKC-α.SKI V (10μM;for 24 hours) inhibits cancer cell proliferation and induces apoptosis.SKI V (0.2,1,5μM;pretreated for 1 hour) decreases phospho-Akt and phospho-MEK levels.Near-confluent cultures of JC cells are serum-starved for 16 hours,followed by pretreatment SKI V for 1 hour.SKI V has IC50s for inhibition of sphingosine kinase (SK) and tumor cell proliferation of -2μM.SKI V (20μg/ml) inhibits not only purified but endogenous SK in in MDA-MB-231 cells.SKI V (0.2,1,5μM) inhibits intracellular S1P formation in JC cells in a dose-dependent fashion.

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 )
母液,添加 300 μLPEG300
混匀澄清,再加 50μLTween80, 混匀澄清,再加 600μLSaline/PBS/ddH2O
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。
