Product Applications The following graph shows the shear modulus G' (Pa) of PhotoDextran ® at a 5% solution. The solution was prepared following the directions for use. Irgacure was used as the photoinitiator, and photocrosslinking was performed using 365nm light. The graph shows the hydrogel strength over time throughout continuous photocrosslinking of the solution.

PhotoDextran^® is 1 gram of lyophilized methacrylated dextran. PhotoDextran^® provides 3D hydrogels that can be prepared at multiple concentrations and photocrosslinked (requires a photoinitiator) to provide various gel stiffness. Can be mixed with other photocrosslinkable ECM's.

Product Description Advanced BioMatrix offers PhotoDextran ® , a methacrylated dextran for photocrosslinkable hydrogels or incorporating within photocrosslinkable hydrogels (such as PhotoGel, PhotoCol or PhotoHA). PhotoDextran ® provides native-like 3D gels with unique attributes: It can be prepared at various concentrations and photocrosslinked in a variety of way to provide a truly tunable gel stiffness. PhotoDextran ® can be ordered by itself (1 gram lyophilized sterile powder), or as a kit that comes with a photoinitiator for photocrosslinking (see table below): Item Catalog Number Photoinitiator Included PhotoDextran #5311 N/A PhotoDextran with Irgacure #5331 Irgacure (365nm) PhotoDextran with LAP #5332 LAP (405nm) PhotoDextran with Ruthenium #5333 Ruthenium (400-450nm) Once solubilized, the PhotoDextran ® can be stored at 2-10°C for 1 month.
