Product Description

Polyethylene Glycol Diacrylate (PEGDA) hydrogels are powerful tools for uncovering basic cellular biology because they are considered biologically inert (“blank slate”) and their mechanical properties can be varied over a large range of moduli.

PEGDA is an emerging scaffold for tissue engineering and regenerative medicine since polymerization can occur rapidly at room temperature and requires low energy input, has high water content, is elastic, and can be customized to include a variety of biological molecules.

PEGDA is a crosslinker repeating polymer crosslinker and is >80% acrylated. It can be used as a thiol-reactive crosslinker in our HyStem systems at low concentration, or can be used to make a PEGDA-only hydrogel in the presence of a free-radical chain photoinitiator and light source. PEG-only gels do not typically support cell attachment without the incorporation of cellular attachment sites.

Regular and 3-D cell culture
Tissue engineering

Store PEGDA in the original vial unopened at -20°C for up to one year. Reconstituted PEGDA solutions can be stored at -20°C for ~ one month.


Directions for Use

PEGDA is prepared by dissolving the lyophilized solid in the DG Water. PEGDA hydrogels (1 mL) should be prepared in the following manner:

  1. Allow the PEGDA to come to room temperature.
  2. Under aseptic conditions add 1.0 mL of DG Water to 100 mg of PEGDA vial for a 10% (w/v) solution.
  3. Invert several times to dissolve. The solution will be clear and slightly viscous.
  4. To sterilize, filter through a 0.2 micron filter.
  5. Add desired volume of photoinitiator to PEGDA. Place the vial on a rocker or shaker and allow solids to completely dissolve (approximately 10-20 minutes).
  6. Keep solution protected from light until ready to crosslink. Pipette solution into desired format (i.e. 96 well plate) and photocrosslink.
  7. Hydrogel properties may vary depending on time of exposure and type of light. Ensure the Photocrosslinking light is in close proximity to the hydrogel solution.
  8. Freeze unused PEGDA solution at -20 °C and protected from light.
