VitroGel® RGD is a ready-to-use tunable hydrogel system modified with a high concentration of RGD cell adhesive peptide, promoting the cell attachment and cell-matrix interactions during the 3D cell culture. Get high levels of integrin-binding activities to promote intercellular networks even after hydrogel dilution.
Mix & Match – 3D Cell Culture Your WAY!
VitroGel® RGD is one of the families of the xeno-free tunable VitroGel system. This hydrogel can mix with other versions of VitroGel such as VitroGel® IKVAV, VitroGel® YISGR, VitroGel® MMP and VitroGel® COL to create the customized multi-functional hydrogel. Using this flexible and powerful hydrogel system, scientists get full control to manipulate the micro-environment for 3D cell culture and more!
VitroGel closely mimics the natural extracellular matrix (ECM) environment, creating a functional and optimized environment to make cells feel like at home. The hydrogel system is ready-to-use at room temperature, has a neutral pH, transparent, permeable and compatible with different imaging systems. The hydrogel strength can be adjusted with VitroGel® Dilution Solution. The solution transforms into a hydrogel matrix by simply mixing with the cell culture medium. Cells cultured in this system can be easily harvested out with our VitroGel® Cell Recovery Solution. The hydrogel can also be tuned to be injectable for in vivo studies.
From 3D cell culture, 2D cell coating to animal injection, VitroGel makes it possible to bridge the in vitro and in vivo studies with the same platform system.

Frequently Asked Questions

- How to prepare the cell suspension to mix the hydrogel? Shall I add serum?
If cells cultured in a complete cell culture medium, which is supplement with 10% FBS or other critical supplements, please prepare the cell suspension using the following methods before mixing it with the hydrogel solution.
- Prepare the cell suspension with 2X concentration (e.g. 100K), and mix with 100% FBS at 1:1 (v/v) ratio to get 1X cell suspension (50K) with 50% FBS.
- Mix the diluted hydrogel solution with the cell suspension from above at 4:1 (v/v) ratio to get the final cells in the hydrogel at 10K with 10% FBS supplement.
If serum plan is an important role in your traditional cell culture, it is also important for 2D coating and 3D culture. Adding serum supplements in the hydrogel and adjusting the final serum concentration to the target level would support cell growth in the hydrogel system.
- How do I adjust the hydrogel formation time?
– If VitroGel needs to be diluted more than 1:3 ratio, a longer waiting time (20-30 min) may be needed for soft gel formation. Using a higher volume of cell culture medium for mixing would help to accelerate the process of hydrogel formation.- If the hydrogel solidifies too fast after mixing with culture medium (showing as small solid gel chunk), adjust the mixing ratio by using less cell culture medium. For example, if mixing 4 mL diluted hydrogel solution with 1 mL cell culture medium lead to the solid gel chuck (particles), then mixing 4 mL diluted hydrogel solution with 0.5-0.8 mL cell culture medium would help to solve the issue.- On the other hand, if the hydrogel formation is too slow, which may happen when using low hydrogel concentration at 1:3 or 1:4 dilution or using a cell culture medium with very low ionic concentration, adjust the mixing ratio by using more cell culture medium. For example, if mixing 4 mL diluted hydrogel solution with 1 mL cell culture medium lead to a slow hydrogel formation, then mixing 4 mL diluted hydrogel solution with 1.5-4 mL cell culture medium would help to solve the issue.
- How do I adjust the stiffness of the final hydrogel?
The stiffness of the final hydrogel can be adjusted by diluting the hydrogel solution before mixing with cell culture media. Our VitroGel Dilution Solution can help to adjust the hydrogel concentration. Please read the “First-time User Note” to learn how to prepare different VitroGel dilutions. If you need a higher hydrogel stiffness than the original product, please contact us at email@example.com.
- Can I harvest cells from the hydrogel after 3D culture?
Yes, the cells can be harvested after 2D coating or 3D culture by using the VitroGel Cell Recovery Solution. VitroGel™ Cell Recovery Solution is a ready-to-use, enzyme-free solution to harvest 2D or 3D cultured cells from hydrogel fast and safely. The solution is compatible with the VitroGel hydrogel system and can recover cells from VitroGel in 15 minutes. VitroGel Cell Recovery Solution is room temperature stable, has a neutral pH and works at 37 °C operating temperature. The solution can maintain high cell viability during the recovery process. Cells can be sub-culture in both 2D and 3D culture after recovery.

Rheological properties of VitroGel RGD with DMEM medium. A) – C) The gel formation curve after mixing with DMEM (A), DMEM/F-12 (B), and RPMI (C) media. VitroGel RGD was diluted at 1:0,1:1, 1:2 and 1:3 (v/v) with VitroGel Dilution Solution (Type 1) and then mix with media at 4:1 (v/v) ratio; D) – F) The gel strength after 24 hrs incubation in DMEM (D), DMEM/F-12 (E), and RPMI (F) media. The hydrogel was prepared as method A and incubated at 37°C CO2 incubator for 24 hrs before the rheological test. (10 ~ 4000 Pa of G’ of regular products at dilutions. Customized high concentration product to reach over 20K Pa)
3D culture of OP9 cells in both VitroGel 3D-RGD and VitroGel RGD-PLUS. (both hydrogels have been prepared at 1:3 dilution with VitroGel Dilution Solution (Type 1), The images were taken on day 2 and 7) VitroGel RGD-PLUS has better support for OP9 cell proliferation and cell-cell communication. The stronger cell-matrix interactions help the cells to form the cell-networking structure.
3D view of OP9 cells growth in VitroGel 3D-RGD and VitroGel RGD-PLUS. Cell networking structure formed in VitroGel RGD-PLUS and only single cell suspension has been observed in VitroGel 3D-RGD.
3D culture of U87-MG cells in both VitroGel 3D-RGD and VitroGel RGD-PLUS. Cells can grow in 3D hydrogel at 1:1 and 1:3 dilution of both hydrogel. However, the morphologies of the 3D cell culture are very different. Unlike the spheroids structure in VitroGel 3D-RGD, U87-MG cells perform better cell networking structure and the cell morphology in VitroGel RGD-PLUS indicates a better cell-cell and cell-matrix interaction.
