Catalog number 122000-50.1G
Price for 122000-50.1G
Size / count 1 g
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.
The catalog number for Ɑ-Methoxy-ω-Squaric Acid Ester Amido PEG is 122000-50.1G.
Ɑ-Methoxy-ω-Squaric Acid Ester Amido PEG is available in the following size(s): 1 g.

Some products, including certain cell lines and biologics, require dry ice for transportation, which carries an additional fee shown clearly in your quotation. Dry ice delivery isn’t always possible to every destination due to transit time or local restrictions, so we check feasibility in advance and you must store the goods at the correct temperature the moment they arrive.
Cross-reactivity data, based on available testing, is listed under the reactivity section of the datasheet. Contact us if you need reactivity confirmed for a species not listed.
Yes, if this product requires dry ice or is classed as hazardous for transport, the additional fee will be explicitly shown in your quotation before you confirm the order, so there are no surprise charges later.
