MAL-PEG12-Tris-(PEG11-amido-MAL)3 is a branched, single molecular weight, thiol-reactive, discrete PEG product. It is designed to join up to four molecules via a malemide-thiol reaction. Buikt around a tris core and terminated on each arm with a thiol-reactive group, this homotetrafunctional crosslinker is 96 atoms long from one malemide to another.
