Application

Gelatin has received significant attention in the biomedical field due to its inherent bioactivity. Functionalized gelatin can be cross-linked with the formation of covalent bonds into highly crosslinked structures, such as hydrogels. Recent literature suggests that radical-mediated polymerized hydrogels may not be ideal for cell and protein encapsulation due to radical-mediated damage, hindered molecular transport, or altered cell-cell/cell-material interactions. Thiol-modified gelatin can be used to form hydrogels with multifunctional norbornene or allyl crosslinkers via thiol-ene click or Michael-addition reactions.
To improve solubility in water, heat to 40°C and stir for 10-15 minutes.

Caution

Material should be handled under nitrogen - air/oxygen & moisture are to be avoided.
