Acid-PEG3-PFP ester is a PEG derivative containing a carboxylic acid and PFP ester end group. The carboxylic acid can be reacted with amines in the presence of activators such as EDC and DCC to form a stable amide bond. The PFP ester can also react

Acid-PEG3-SS-PEG3-acid is a cleavable PEG linker with carboxylic acid groups at both terminus. The disulfide bonds can be cleaved via a reduction reaction using Dithiothreitol (DTT) reagent. The terminal carboxylic acids can be reacted with primary
