Description

Features and Benefits

Bis-dPEG^®₅-PFP ester has 2,3,4,5,6-pentafluorophenyl (PFP) moiety that allows conjugation to two different moieties, each containing free amines. The single molecular weight dPEG^® spacer (21.7 Å) provides precise distance control between conjugated moieties. PFP ester is more reactive to amines than the NHS ester and are more stable than the NHS esters towards hydrolysis.
