Bis-MAL-Lysine-dPEG®4-TFP ester, product number 10631, is a unique crosslinker from Quanta BioDesign, Ltd. The alpha (α) and epsilon (ε) amines of lysine are functionalized with sulfhydryl-reactive maleimidopropyl groups. The carboxylic acid tail of lysine is conjugated to a single molecular weight, discrete polyethylene glycol (dPEG®) spacer containing an amine-reactive 2,3,5,6-tetrafluorophenyl (TFP) ester. The distance from the carbonyl carbon of the dPEG® spacer to the reactive site of the α-amine-conjugated maleimide group is 25 atoms (18.773 Å) long. The distance from the carbonyl carbon of the dPEG® spacer to the reactive site of the ε-amine-conjugated maleimide group is 29 atoms (26.105 Å) long.
