Price for 12750-50.500MG
Size / count 500 mg
PEGs with an active ester functional group at one end allow for selective and covalent attachment to other molecules with complementary functional groups, such as primary amines on proteins, peptides, or other molecules. To a lesser extent they are reactive towards thiols or hydroxyls (to form thioesters or esters) . Squaric Acid Ester Amido PEGs are a novel class of reactive and chemoselective PEG crosslinking reagents. The squaric acid PEGs are chemoselective towards the amino groups of Lysin in protein PEGylation whereas the guanidine function of Arginine, the hydroxyl group of Serine and the imidazole function of Histidine are not affected. Compared to other active esters, these PEGs are remarkably stable in aqueous media and not easily hydrolyzed.

Shelf life and expiration dates vary by product and are shown on the product listing and label. Products used beyond their expiration date are not eligible for performance-related returns or refunds, so please check the lot number and expiry before use.
The expression system, such as E. coli, HEK293, or insect cells, is listed on the datasheet under production details, which can affect post-translational modifications relevant to your application.
As a consumer, you have a 14-day right of withdrawal from receipt under EU consumer protection law, submitted via our withdrawal/cancellation request form. Note this applies to unused, undamaged products, and doesn’t override the expiry/storage conditions on performance-based claims.
