DyNAtrix® vs. Traditional Matrices: A Comparison
Team Dynamic Matrices | 6 December 2025
Choosing a matrix for 3D cell culture usually comes down to a trade-off labs have learned to live with: the familiarity of a traditional, animal-derived basement membrane matrix like Matrigel® (Corning), or a synthetic system such as VitroGel® (TheWell Bioscience), NexaGel® (Sartorius), or TrueGel3D™ (Sigma-Aldrich). DyNAtrix was built to remove that trade-off entirely, a fully synthetic hydrogel that handles like the animal-derived matrices researchers already know, without the batch variability, undefined composition, or cold-chain handling that come with them, and with a mechanical control most synthetic alternatives don't offer. Here's how they compare, feature by feature and by name.
Key features
| Feature | DyNAtrix® | Animal-Based ECM |
|---|---|---|
| Composition | Pure synthetic, DNA-crosslinked hydrogel. No animal- or human-derived proteins, no undefined growth factors; every component is specified. | Extracted from mouse-tumor basement membrane (e.g. Engelbreth-Holm-Swarm tumor). A complex, largely uncharacterized mixture of structural proteins and growth factors that varies from lot to lot. |
| Handling temperature | Ships and stores at 4°C, standard refrigeration only; no dry ice or -20°C freezer needed. Mix directly from 4°C storage with your cell suspension, then incubate at 37°C. | Typically requires -20°C freezer storage and dry-ice shipping. Must be thawed slowly and kept on ice throughout handling to prevent premature gelation. |
| Mechanical tunability | Stiffness and stress relaxation are independently tunable across a wide range, so the matrix can be matched to the tissue being modeled. | Fixed, soft mechanical properties set by the source tissue. Not independently tunable. |
| Optical clarity | Optically transparent with no autofluorescence. Compatible with confocal, light-sheet, and standard fluorescence imaging directly in the gel. | Naturally occurring proteins can autofluoresce and scatter light, which complicates high-resolution imaging. |
| Batch-to-batch consistency | Manufactured from chemically defined precursors to the same specification every batch. | Sourced from tumor tissue extracted from different animals. Lot-to-lot composition variability is a well-documented cause of irreproducible culture results. |
| Animal-free / NAMs alignment | Fully synthetic and xeno-free. Aligns with the FDA's New Approach Methodologies (NAMs) initiative. | Animal-derived by definition. Does not meet xeno-free or animal-free research requirements. |
Operation & workflow
| Feature | DyNAtrix® | Animal-Based ECM |
|---|---|---|
| Protocol | Mix precursor B+ with precursor X and your cells, then incubate at 37°C. Deliberately designed to mirror standard animal-derived-matrix handling, so switching doesn't mean re-training your team. | Thaw slowly on ice, keep cold throughout handling, then incubate at 37°C to gel. |
| Cell harvesting | Enzyme-based, clean release: degrade with DNase I in cell culture medium at 37°C, typically within 30 minutes, preserving high cell viability for downstream work or passaging. | Recovery typically requires dedicated enzymatic or chemical dissociation reagents, often at cold temperatures and over longer incubation times. |
| Imaging & staining | Image directly in the gel. Fixation and staining can be performed in place, without recovering cells first. | Undefined matrix components can interfere with staining and contribute to background signal. |
| Vessel compatibility | Works in the plates, dishes, and vessels you already use, no special labware needed. | Generally vessel-agnostic as well, though cold-chain handling adds extra steps at the bench. |
Applications
| Feature | DyNAtrix® | Animal-Based ECM |
|---|---|---|
| Cell types & organoid models | Validated across iPSCs, MSCs, MDCK, MDA-MB-231, MCF-10A ER-Src, KG-1, and chondrocytes, plus placenta, kidney, and brain organoid models, and glioblastoma. | Broad historical use across many cell types, but with matrix-driven variability that complicates cross-batch comparisons. |
| Bioprinting | Self-healing and injectable. Suitable for extrusion bioprinting as a bio-ink. | Limited printability: fixed viscosity and temperature sensitivity constrain most extrusion setups. |
| Mechanobiology studies | Independent control of stiffness and viscoelasticity makes it possible to isolate mechanical variables from biochemical ones. | Non-tunable mechanics make it difficult to separate mechanical effects from the matrix's other undefined variables. |
Storage & sourcing
| Feature | DyNAtrix® | Animal-Based ECM |
|---|---|---|
| Storage | Precursor stock is stable long-term (multi-year); the ready-to-use kit is stable at 4°C for 6+ months. Standard refrigeration only, no -20°C freezer required. | Typically requires -20°C storage, careful thawing, and use within a limited working window once thawed. |
| Long-term culture | Supports long-term culture beyond 60 days without re-embedding. | Degrades over shorter culture windows; longer studies often require re-embedding. |
| Sourcing | Fully synthetic, with no animal tissue involved in production. | Derived from animal tumor tissue. |
DyNAtrix vs. named synthetic and animal-derived matrices
| Matrix (vendor) | Composition | Stiffness range | Independent stress-relaxation tuning | Animal-free |
|---|---|---|---|---|
| DyNAtrix (Dynamic Matrices) | DNA-crosslinked synthetic polymer | 1–100 Pa (Minimal Discovery Kit); 1–400 Pa (advanced tier) | Yes — independently tunable, under 1s to over 100,000s | Yes |
| Matrigel® (Corning) | Extracted from EHS mouse-tumor basement membrane; over 1,850 proteins identified, composition varies by lot | Fixed by source tissue, not independently tunable | No | No, animal-derived |
| VitroGel® (TheWell Bioscience) | Synthetic, tuned via a separate dilution solution | 10–4,000 Pa (up to >20,000 Pa) | Not publicly stated as independent of stiffness | Yes, animal origin-free |
| NexaGel® (Sartorius) | Synthetic, xeno-free, functional ligand modification | 10–4,000 Pa | Not publicly stated as independent of stiffness | Yes, xeno-free |
| TrueGel3D™ (Sigma-Aldrich) | Synthetic, MMP-cleavable crosslinker chemistry | ~150–5,000 Pa (0.15–5 kPa shear modulus) | Not publicly specified | Yes, chemically defined synthetic |
Competitor specifications are sourced from each vendor's own published product documentation as of September 2026 (see References below) and may change; DyNAtrix figures reflect current product specifications, as stated on this site.
The distinction worth noting: all four synthetic options above are animal-free, so sourcing alone no longer separates them. What separates DyNAtrix is mechanical control. VitroGel, NexaGel, and TrueGel3D publish tunable stiffness ranges; none of the three publicly describe stress relaxation (viscoelasticity) as independently tunable from stiffness. DyNAtrix's DNA-crosslinker chemistry controls both properties separately, which matters for mechanobiology work where stiffness and relaxation need to be varied one at a time.

None of this means animal-derived matrices don't have their place. They remain the most extensively characterized option in the literature, simply because researchers have used them the longest. But for labs that need reproducible, well-defined culture conditions, or that are moving toward regulatory-facing work, a synthetic system built to specification removes an entire category of variability from the experiment. DyNAtrix was built to make that switch as close to a drop-in replacement as possible.
FAQs
For most standard 3D culture and organoid protocols, yes. The mixing and incubation steps are deliberately designed to mirror standard animal-derived matrix handling. Some protocols may need minor adjustment for gelation time or seeding density, which our protocols page and support team can help with.
Yes. The core issues, animal sourcing, undefined composition, batch-to-batch variability, and cold-chain handling, apply broadly to basement-membrane matrices derived from animal tissue, not to one specific brand.
All four are synthetic and animal-free, so the difference isn't sourcing, it's mechanical control. VitroGel®, NexaGel®, and TrueGel3D™ publish tunable stiffness ranges. DyNAtrix is the only one of the four that also publishes independently tunable stress relaxation (viscoelasticity) alongside stiffness, letting you match both properties to the tissue you're modeling rather than stiffness alone.
No. DyNAtrix ships pre-formulated at a set stiffness and relaxation profile for each kit tier, the Minimal Discovery Kit (1 to 100 Pa) or the advanced/custom tier (1 to 400 Pa), rather than requiring a separate dilution step to reach your target stiffness.
