3-Maleimidopropionic acid-PFP ester (CAS 138194-55-5)

3-Maleimidopropionic acid-PFP ester (3-MPA-PFP) represents an innovative ester derived from the combination of maleimidopropionic acid and paraformaldehyde. This particular ester has gained significant recognition as a cross-linker in bioconjugation reactions, owing to its capacity to establish a stable covalent bond between two molecules. The diverse scientific research applications of 3-Maleimidopropionic acid-PFP ester have been extensively explored. Its utility in protein labeling allows for the covalent attachment of fluorophores or other labels to proteins, enabling the study of protein-protein interactions. Moreover, it finds application in immunoassays such as ELISAs, where it aids in the detection of target proteins or other molecules. The mechanism of action of 3-Maleimidopropionic acid-PFP ester is rooted in its ability to forge a stable covalent bond between two molecules. This is achieved through the reaction between the maleimide group of 3-Maleimidopropionic acid-PFP ester and the amino group of the target molecule. This highly specific reaction results in the formation of a resilient covalent bond that withstands chemical or enzymatic cleavage.
