Product Information

Description Bis-Sulfone-PEG2-acid is a PEG linker with a sulfone and acid end group. The sulfone group can be conjugated with thiol groups of proteins. The terminal carboxylic acid can react with primary amines in the presence of activators such as EDC and HATU to form stable amide bonds. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media.
