Choose 'Spontaneous' if you are using SG-Dextran, SG-PVA, Mal-Dextran or Mal-PVA as thioreactive polymer. Choose 'Photo-Crosslinking' if you are using N-Dextran.
Use a ratio of 1:3 for most applications. If you need faster gel formation, you can use a ratio of 1:2 or enter your individial concentration of LAP in Section 3. Be aware that higher LAP concentrations increase the risk of cytoxicity.
