PBS is not recommended. You can even store the gel (w/o cells) in water.

For cryopreservation, use both DMSO and Ca2+.

Sodium alginate is a natural polysaccharide product extracted from brown seaweed that grows in cold water regions. Sodium alginate is a gum, extracted from the cell walls of brown algae. Please have a look at enclosed PDF...

I find normal saline to be a helpful starting point for all solutions. Tonicity will be important to prevent swelling. If you makeup the alginate in normal saline and you make the gelation bath with a divalent cation added to that same normal saline solution you help minimize swing in tonicity. Here is a link to a protocol that may prove useful. Full version on researchgate. https://www.nature.com/articles/nprot.2011.352

Hi Alberta,
Once the hydrogel is formed, it is essential to maintain the scaffold in buffered medium with calcium. You can use regular cell culture medium or DPBS w/Ca++ and Mg++.
Hope this helps...
