ABSTRACT:
A new class of polyalkylene oxide vinyl sulfone reagents is described. Also described are a method by which these reagents can be prepared as well as a method for using them in hydrated media for the modification of proteins. The novel polymer-to-protein conjugates made by reacting these reagents with proteins have advantages over similar conjugates prepared with prior art reagents in that they are more stable against hydrolysis and retain the positive charge carrying capacity at amine sites at which the modifying reagents are attached.
