Mal-PEG5-PFP ester - CAS 1807512-46-4

Inquiry

Mal-PEG5-PFP ester is a PEG linker containing maleimide and PFP moieties. Maleimide is thiol-reactive and reacts between pH 6.5 and 7.5 to form thiol ester bonds. PFP moiety is amine-reactive and is less susceptible to undergoing hydrolysis. The hydrophilic PEG linker increases the water solubility of a compound in aqueous media.
