Multi-arm PEGs

Multi-Arm PEG product is a unit smart cross-linker widely studied in the medical and bioorganic fields.  Multi-arm PEG derivatives can be cross-linked into hydrogels. PEG hydrogels have a variety of applications in medical devices and regenerative medicine. They are especially of interest for the controlled release of drugs, for 3D cell culture, and for wound sealing and healing.

Biopharma PEG supplies multi-arm PEG linkers with different branching and functionalities with MW 2k, MW 5k, MW 10k, MW 20k and MW 40k.

▶ 2-Arm PEG (Y-shape PEG, branched PEG), such as Y-shape-PEG-NHS
▶ 4-Arm PEG, such as 4-ArmPEG-SG4-ArmPEG-SS4-ArmPEG-NH2, etc
▶ 8-Arm PEG, such as 8-ArmPEG-SG, 8-ArmPEG-SS8-ArmPEG-Mal, etc

The total molecular weight reported for the multi-arm PEGs is the sum of the molecular weights of the PEG chains on each arm. Multi-arm star PEG products with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis.
