概述
甘油被用于聚丙烯酰胺凝胶电泳的样品制备和凝胶形成。甘油（5-10％）可增加样品的密度，使样品在凝胶样品孔的底部分层。甘油还可用于帮助浇注梯度凝胶以及作为蛋白质稳定剂和储存缓冲液的组分。应用：
甘油是无味、无色、粘稠的甜味液体。它可以是天然来源的，也可以来自石化原料。甘油具有广泛的应用，是自然界中最有价值和多功能的化学物质之一。它可用作润肤剂，溶剂，甜味剂以及用于药物配方、化妆品、食品和卫生用品中。它非常稳定，可以在常温下储存；也没有刺激性，对环境无不良影响。
Glycerol is odourless, colorless, viscous in nature, and exists as a sweet tasting liquid. It can be derived naturally as well as from petrochemical feedstock. Glycerol has a wide variety of applications, and is one of the most valuable and versatile chemical substances in nature. It can be used as an emollient, solvent, sweetening agent, in pharmaceutical formulations, cosmetics, foodstuffs and toiletries. It is very stable and can be easily stored under normal temperature; also it is non-irritating and has no adverse impact to the environment.
Application:
Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel′s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.

生化机理
甘油具有吸湿性，并且因其具有三个亲水性醇羟基而可溶于水。它可以形成分子间和分子内氢键，使其成为一种非常灵活的分子。 甘油的生理作用是由细胞介导的免疫、增加IgG产生和增加组胺释放造成的。 甘油已被用作：
- 结核分枝杆菌和 鸟分枝杆菌 细胞培养过程中的补充剂。
- 酶生物燃料电池设计过程的燃料。
- 在分析中性和酸性聚糖时，与4-HCCA和3-氨基喹啉一起作为液体复合基质。
- 作为快速原子轰击质谱的基质。
- 作为MALDI（基质辅助激光解吸/电离质谱）分析定量研究的液体基质。
