Supporting Information

Description The ToLuminate PEG Photogel kit provides reagents for setting up cell-compatible hydrogels formed by illumination with blue light (365-405 nm) on the basis of the thiol-ene chemistry. Its major components are norbornene-modified dextran (N-Dextran) and the thiol-modified cross-linker PEG-Link. When the two reagents are combined and illuminated in the presence of LAP (Lithium phenyl-2,4,6-trimethyl­benzoyl­phosphinate) thiol groups on PEG-Link are activated and form stable thioether bonds with norbornene groups on N-Dextran. The components are mixed at physiological pH (pH 7.2) for optimal cell compatibility. There is ample time to place the pre-gel solution in any culture dish or container, since gelation starts only after illumination.

Cell adhesion peptides (e.g. 3-D Life RGD Peptide, Cat. No. 09-P-001) can be covalently attached to a portion of the norbornene groups on N-Dextran with the same chemical reaction as PEG-Link to provide a cell-adhesive matrix.

3-D Life AgaFloat (Cat. No. A10-3) can be added to the pre-gel solution to avoid sedimentation of cells before illumination.

Dextran hydrogels crosslinked with PEG-Link can be dissolved by the addition of dextranase (3-D Life Dextranase, Cat. No. D10-1), which allows the recovery of chemically fixed or live cells for post-culture analyses (e.g. RT-PCR) or for further cultivation.
