PEG2K-Se-Se-PEI20K

PEG-Se-Se-PEI,PEI-Se-Se-PEG,The disulfide bonds linking the PEI and Se atoms in the conjugate are sensitive to the intracellular environment,specifically the high levels of reductive agents such as glutathione.This sensitivity allows for the controlled release of the payload (e.g,genes or drugs) in the target cells.The reduction of the disulfide bonds leads to the detachment of the payload from the delivery system,facilitating its release and subsequent biological activity.
