体内研究 |
Goldfishes which are treated with salt have significantly lower mucus weights at 25h.Goldfishes treated with Polyvinylpyrrolidone (PVP) have significantly higher mucus weights at 25h.Koi treated with salt and Polyvinylpyrrolidone (PVP) has significantly lower mucus weight at 1 and 25h.Control koi has significantly higher mucus at 25h.At the end of 2 weeks,it is determined that the three koi treated with salt and Polyvinylpyrrolidone(PVP) remain healthy and show a higher degree of healing than other treatment koi and the control group. |

动物实验: |
|
|
Each fish within a tank serves as a replicate.Treatments are designated as Polyvinylpyrrolidone (at a dose of 10mL/10 gallon) and saline/salt at 3g/L.A control group that does not receive any chemical is also included in the study.All fishes from each treatment group are sampled at 0 min,15 min,1h,4h and 25h.At each time interval,all fishes from each treatment group are anaesthetized using buffered tricaine methanesulfonate,weighed,and slime is scraped from one 1 cm2 area over the epaxial musculature using a preweighed plastic coverslip. |

Lot/Batch Number
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。
