ILEX LIFE SCIENCES LLC Cellendes 3-D Life PVA-PEG Hydrogel SG Ready-To-Design Kit (1 Kit)
3-D Life is the most flexible system for biomimetic hydrogel design. It uses two polymers that form a hydrogel by covalent crosslinking at ambient temperature. The chemical reaction is non-toxic to cells and occurs rapidly, preventing cell settlement before the gel is formed. 3-D Life PVA-PEG Hydrogel SG Kit provides reagents for setting up slow gelling, cell-compatible hydrogels for 3D cell cultures. Components are mixed at physiological pH 7.2 for optimal cell compatibility. Slow gelation allows enough time to manipulate the solution before onset of gel formation. Peptides (e.g. 3-D Life RGD Peptide, Cat. No. 09-P-001) can be covalently attached to a portion of the SH-reactive groups of SG-PVA to provide a cell-adhesive matrix. One kit allows formation of up to 2 ml hydrogel depending on gel stiffness. Manufactured in Germany by Cellendes GmbH.
