Description
3-D Life SG-Dextran is a component of the 3-D Life Hydrogel system. It contains dextran functionalized with thiol-reactive groups (SG-Dextran) that 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.
When crosslinked with PEG-Link or CD-Link, Dextran-based 3-D Life Hydrogels can be dissolved by the addition of dextranase (3-D Life Dextranase, Cat. No. D10-1), which allows the recovery of chemically fixed or live cells for post-culture analyses (e.g. RT-PCR) or for further cultivation. NOTE: Dextran hydrogels crosslinked with HyLink cannot be dissolved by dextranase.
The included 10x CB Buffer (pH 7.2) is a buffer to control pH and osmotic conditions during gel formation in the presence of cells.
For more information and instructions, please consult the General Protocol GP-2 "Preparation of 3-D Life Slow Gelling Hydrogels" and the 3-D Life Hydrogels User Guide, which may be downloaded below.
Application
3D cell cultures; embedment and immobilization of cells or tissues and subsequent recovery of specimens by hydrogel dissolution.
Quantity
Allows formation of up to 6 ml 3-D Life Hydrogel depending on the stiffness of the gel, if used together with thiol-functionalized polymers (3-D Life PEG-Link or CD-Link).
