Medicine
Polyethylene Glycol 6000
Product code RXSOL-95-8122-025
Range of Avg. Molecular Weight 5400-6600
Description
PEGs are soluble in water and most organic solvents. The reason for for using PEGs with large molecular weight is that smaller PEGs can diffuse through the cell wall and are even taken up by plant cells and distributed through the plant, which may influence the results. larger than 6,000 (PEG 6000) are inert, non-ionic and cell impermeable. to simulate osmotic stress.
Application
Application
Polyethylene glycols are non-toxic, odorless, neutral, lubricating, nonvolatile and nonirritating and are used in a variety of pharmaceuticals and in medications as a solvent, dispersing agent, ointment and suppository bases, vehicle, and tablet excipient.
Precautions
Precautions
The addition of PEG to a protein solution increases the chemical potential of the protein. Precipitation of the protein occurs when its chemical potential exceeds the level of a saturated solution.
