体外研究 |
The EverFluor FL Verapamil (EFV) uptake by TR-iBRB2 cells is inhibited by cationic drugs,and inhibits by verapamil in a concentration-dependent manner with an IC50 of 98.0μM. |
|
体内研究 |
Given orally Verapamil is useful for the prophylaxis of atrioventricular reentry tachycardia,and also in modulating the atrioventricular nodal response in atrial fibrillation.Verapamil is injected i.v.into a femoral vein prior to ischemia.Verapamil (1mg/kg) significantly decreases the incidence of ventricular arrhythmias including premature ventricular contractions (PVC),ventricular tachycardia (VT) and ventricular fibrillation (VF) for 45-min coronary artery occlusion.Total arrhythmia scores are significantly increased when the heart is subjected to ischemia.Verapamil (1mg/kg) significantly prevents the enhancement of total arrhythmia scores induced by ischemia. |
推荐实验方法(仅供参考)
|
细胞实验: |
|
|
Cells (1×105) are treated with 10nM Bortezomib and/or 70µM Verapamil for 16 hours and incubated for another 4 hours with Alamar-Blue.Activity of the mitochondrial dehydrogenase results in conversion of the coloring,which is followed by measurement of the absorption using a spectrophotometer. |
|
|
动物实验: |
|
|
Rats Adult male Sprague-Dawley (SD) rats (250−350g) are used.Verapamil (1mg/kg) is injected i.v.into a femoral vein 10 min prior to ischemia.A sham group undergoes the same surgical procedures,except the suture underneath the LAD is left untied.In another series of experiment,arrhythmia is induced by Bay K8644,an L-type calcium channel agonist,at a dose of 0.1mg/kg given i.v.into the FV.Verapamil (1mg/kg) is administered 10 min prior to Bay K8644.All injections are performed within 30 sec. |

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。
