Product Description

Advanced BioMatrix offers PhotoPluronic® - Pluronic F-127 diacrylate. PhotoPluronic® is water soluble and can be photocrosslinked in the presence of a photoinitiator (not included) to form a robust hydrogel. PhotoPluronic® is also unique in that it can transition from liquid to gel by incubating at 37C, or from gel to liquid by refrigeration at 2-8C. This process can be repeated multiple times (prior to photocrosslinking). The kit comes with 2 grams of non-sterile powder.

Directions for Use

  1. Solubilize PhotoPluronic® by adding cold water or 1X PBS. Recommended concentrations range from 5-40%.
  2. Continue mixing (shaker table or rotator plate) in a cold environment (2-10C) until fully solubilized.
  3. Add desired photoinitiator at this step if desired. Recommended photoinitiator concentrations can be found below.
  4. Sterile filter through 0.45 micron button filter prior to use if sterility is desired. Keep Pluronic cold, as it will drastically increase viscosity or form a gel as it warms up.
  5. If there are bubbles, centrifuge the pluronic. 
  6. At this stage, the PhotoPluronic® can be added to a syringe for 3D bioprinting, or used for the desired application. 
  7. Note:  Longer exposure allows more crosslinking, though each cell type withstands different degrees of UV light and free radical exposure (generated by the photoinitiator) that mediates crosslinking.
