TrueGel3D Hydrogel Kits

CD cell-degradable crosslinker and RGD peptide




TRUE1-1KT contains lyophilized RGD degradable polymer and CD cell-degradable crosslinker with reconstitution buffer and water.


Suitable for 3D-culture of various cell types, spheroids and tissue samples. It has been used for cell migration and invasion studies, co-culture experiments (tumor cells with fibroblasts) and cell growth and differentiation studies.


Avoid prolong exposure of CD cell-degradable crosslinker to air.

Features and Benefits

• Easy to use and pre-configured
• Gel with soft stiffness of 400 Pa
• Contains RGD degradable polymer for cell attachment
• Allow cell recovery and post-culture analyses

General description

The gel is formed by crosslinking of modified RGD degradable polymer with CD cell-degradable crosslinker. At physiological pH, the thiol groups of CD cell-degradable crosslinker interact with thiol reactive groups on RGD degradable polymer to form soft gel. The CD cell-degradable crosslinker is composed of matrix metalloprotease (MMP)-cleavable peptide (Pro-Leu-Gly-Leu-Trp-Ala), which allows cells to spread and migrate by secreting matrix metalloproteases (MMP1, MMP3, MMP7 and MMP9).

Gel can be further dissolved by TrueGel3D Enzymatic Cell Recovery Solution (TRUEENZ-500UL) for post-culture analysis including RT-PCR, western blots and other molecular biological studies.
