Product Information

Description	Tosylate-PEG-Tosylate has two identical activated tosyl also called toluenesulfonyl groups. Homobifunctionalized PEG derivatives have wide applications in peptides, proteins, lipids, other small molecules and surface modifications. Drug PEGylation can alter its dispersity and solubility in aqueous solutions. PEG modification can create a spatial barrier around the drug, reduce the enzymatic hydrolysis of the drug, avoid the rapid elimination of kidney metabolism, and allow the drug to be recognized by cells of the immune system.
Solubility	Soluble in water, DMSO and DMF. Freshly prepared before use.
Storage	-20°C for long-term preservation, keep in dry and avoid sunlight. Avoid repeated freezing and thawing.
