What is Bis-PEG4-acid?
Description
Bis-PEG3-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
