Product Information

Description	NH2-PEG-COOtBu has two different activated terminal groups, one amine and one tertiary butyl ester protected carboxylic acid. Heterobifunctionalized PEG derivatives are used in cell culture, pharmaceutical research, drug delivery and release, nanotechnology and new materials. Heterobifunctional PEG can be attached to different molecules or materials to extend the richness of different molecular combinations. Drug PEG modification can alter its dispersion 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.
