Methoxy-poly(ethylene glycol)-block-poly(L-lysine trifluoroacetate) is a linear hydrophilic block copolymer which has a poly(L-lysine trifluoroacetate) section and a non-reactive PEG section. It is a solid soluble in water and polar organic solvents such as DMF. Upon derivatization of the poly(L-lysine trifluoroacetate) part, it can self-assemble into particles in aqueous solution with a hydrophobic poly(L-lysine) core and a hydrophilic PEG shell. Applications for methoxy-poly(ethylene glycol)-block-poly(L-lysine trifluoroacetate) include the conjugation to active molecules for improved activities, the layer-by-layer deposition techniques, and the complexation with nucleic acids for gene expression.

Our methoxy-poly(ethylene glycol)-block-poly(L-lysine trifluoroacetate) has been purified by dialysis, sterile-filtered on 0.2um, lyophilized, and stored under Ar.

Storage Conditions:

Store methoxy-poly(ethylene glycol)-block-poly(L-lysine trifluoroacetate) under the condition of flushing with argon and protecting from light, and below -15°C.
