3-D Life SG-PVA is a component of the 3-D Life Hydrogel system. It contains polyvinyl alcohol functionalized with thiol-reactive groups (SG-PVA). It can be used together with PEG-Link (Cat. No. L50-1 or L50-3) or CD-Link (Cat. No. L60-1 or L60-3) to set up slow gelling, cell-compatible hydrogels. 10 x CB (pH 7.2) buffer allows control of pH and osmotic conditions during gel formation in the presence of cells.
