4arm PEG20K-TK-Mal

4 arm-PEG20K-TK-Mal/4arm-PEG-TK-MAL,MW:20K/4 arm-PEG20000-TK-Mal is a four arm polyethylene glycol maleimide derivative with reactive oxygen species responsive properties. It can be used to construct ROS responsive degradable hydrogel, as a drug sustained release scaffold responsive to tumor microenvironment, to achieve controlled release of chemotherapy drugs. It can be used for surface functionalization modification of nanocarriers, and an intelligent targeted drug delivery system responsive to the tumor microenvironment can be prepared by coupling with thiolated targeting peptides. It can be used for site-specific directed coupling of proteins and peptides, and is widely used in scientific research scenarios such as bioorthogonal labeling and tissue engineering scaffold construction.
