Frequently Asked Questions

Frequently Asked Questions are available for this Product.

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.

Biochem/physiol Actions

Glycerol has been used as
• a supplement during cell culture of Mycobacterium tuberculosis and Mycobacterium avium.
• a fuel during designing enzymatic biofuel cell.
• a liquid composite matrix with 4-HCCA and 3-amino­quinoline for analysis of neutral and acidic glycans.
• a matrix for fast atom bombardment MS.
• may be employed as liquid matrix for the quantification studies by MALDI (Matrix-assisted laser desorption/ionization mass spectrometry) analysis.

Glycerol is hygroscopic in nature and is soluble in water owing to its three hydrophilic alcoholic hydroxyl groups. It can form both inter- and intramolecular hydrogen bonds, making it a very flexible molecule. The physiologic effect of glycerine is due to cell-mediated immunity, increased IgG production and increased histamine release.

General description

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.

Is Product No. G2025 a sterile glycerol product?
Our quality specifications for this product include cell culture testing, but the product is not sterile as it is shipped.
What is the meaning of  "Performance" in your specification sheet for Product No. G2025 (Glycerol)?
The "Performance" test demonstrates that a cell freezing medium prepared using that product maintains the viability of mammalian cells after storing the cells for 5 to 7 days at -196 °C.
What is the concentration of glycerol (e.g., Product No. G2025)?
Based on a density of 1.261 g/mL for glycerol, and a molecular weight of 92.1 g/mol, the concentration of this liquid is 13.7 M.
Can I autoclave glycerol (e.g., Product No. G2025) before using it (for example) for cell culture?
Glycerol can be autoclaved for 20 minutes, as is or in a solution, generally at approximately 50%. (http://www.protocol-online.org/biology-forums/posts/27235.html)
In what solvent is glycerol (e.g., Product No. G2025) most soluble?
Glycerol is miscible with water and alcohol at all concentrations. See: The Merck Index, 12th ed., Entry# 4493.
What is the viscosity of glycerol?
The viscosity of glycerol is 648 Centistokes at 20 Deg C (68 Deg F).
