Description

Poly(Ethylene Glycol) Diacrylamide is a specialized, crosslinkable monomer featuring terminal acrylamide groups linked by a flexible poly(ethylene glycol) (PEG) spacer. This unique structure is critical for creating hydrophilic, biocompatible polymer networks with tunable mechanical properties. It is an essential building block for researchers and manufacturers in the life sciences and advanced materials sectors seeking to develop innovative hydrogels, drug delivery systems, and functional coatings.

Application

• Hydrogel Synthesis: A key monomer for creating PEG-based hydrogels used in tissue engineering scaffolds, wound dressings, and contact lenses.
• Drug Delivery Systems: Used to formulate biodegradable and stimuli-responsive nanoparticle or microparticle carriers for controlled drug release.
• Bioconjugation & Protein Modification: Serves as a heterobifunctional crosslinker for attaching biomolecules (e.g., peptides, antibodies) to surfaces or other polymers.
• 3D Bioprinting Bioinks: A component in photocurable bio-inks, enabling the fabrication of complex, cell-laden structures for regenerative medicine.
• Chromatography Media: Employed in the functionalization of stationary phases to create hydrophilic interaction chromatography (HILIC) columns.
• Surface Coatings: Used to create non-fouling, anti-biofilm coatings on medical devices and implants.

Quality Control

Our Poly(Ethylene Glycol) Diacrylamide is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and assay, to ensure consistency and performance for critical research and production applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, residual monomer, and moisture content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. Under these recommended conditions, the product is stable for at least 24 months from the date of receipt. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
