Figure 4: The thiol-maleimide reaction. (a) The reaction is chemoselective for thiols from pH 6.5 – 7.5. (b) Above pH 7.5, thiol chemoselectivity is lost, and the maleimide moiety begins reacting with free amines (e.g., lysine).

WebPolyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research.
