Maleimide Linkers

Maleimide Linkers


Maleimide Linkers are very popular bioconjugation linkers, they react specifically with sulfhydryl groups to form a stable thioether linkage when the pH is between 6.5 and 7.5.
BroadPharm provide a broad range of maleimide linkers with various functional groups, such as Mal-PEG-alkyne, Mal-PEG-amine, Mal-PEG-NHS ester, Mal-PEG-PFP ester, Mal-PEG-acid, Mal-branched PEG, Mal-PEG-fluorescent dye, and Mal-PEG-biotin. PEG arms in the linkers improve water-solubility of the reagent.
