Solubility: Lansoprazole is practically insoluble in water, sparingly soluble in ethanol, and freely soluble in dimethylformamide. pKa: Hellstrom and Vitols reported that lansoprazole has a pKa of 4.01. Kristl found three reported pKa values of abou Lansoprazole是白色对褐色白色无气味的水晶粉末。
Glycerin is generally safe to use on the skin. However, you should never leave it on your skin for too long in its undiluted state. Its thick, viscous nature will attract dust and pollution to your face so wash it off a little while after application. How does glycerol interact with water?
RNA was extracted by chloroform extraction, precipitated using isopropanol, washed with ethanol and resuspended in 20–30 µl of nuclease-free water. 2–5 µl of resuspended RNA was set aside to run on a gel and the remaining was DNase-treated in DNase buffer (100 mM Tris-HCl,...
