Poly(ethylene glycol) diacrylate (MW 1000)  (Synonyms: PEGDA (MW 1000))

Poly(ethylene glycol) diacrylate (PEGDA) (MW 1000) is a versatile polymer material that is widely used as a building material for hydrogel scaffolds, especially in the fields of tissue engineering and regenerative medicine^[1].

Product Properties:
This product is readily soluble in water and can be prepared into hydrogel precursor solutions of varying concentrations. Adding the photoinitiator LAP (HY-44076) to this precursor solution triggers crosslinking upon illumination, yielding a hydrogel with a certain mechanical strength.
Instructions:
1. Dissolve this product at a concentration of 10-20 (w/w)% in pure water or phosphate buffer at room temperature, depending on the intended use. Add 0.1-0.3% (w/w)% LAP photoinitiator to prepare a gel precursor solution.
2. Add the above solution to the mold and refrigerate. Irradiation under 405 nm light for 30-60 seconds will form PEGDA hydrogel.
