Combine up to three GelMA bases, set the photoinitiator, and add functional components. We prepare it ready to use, ship it at ambient temperature with no cold chain required, and give you a formulation code so you can reorder the same bioink exactly.
Build your custom bioink: blend up to 3 GelMA bases to a combined concentration of ≤20% (w/v) + photoinitiator + additives. 100+ basal formulations for in vitro 3D tissue scaffold fabrication.

Each base adds to the combined GelMA concentration, capped at 20% (w/v).
Ready-to-use formulation, shipped ambient. Final pricing confirmed on quote.
Everything the mixer lets you set, and the ranges we prepare.
Five steps from a blank formulation to a quote.
Cost-effective bioinks for learning and testing bioprinting techniques.

A custom bioink is one formulated for your application rather than sold as a fixed catalog product. In the Cytoink Bioink Mixer you choose the GelMA sources and their concentrations, the photoinitiator level, and any functional components, then receive the result ready to use.
Five bases are available: Porcine GelMA 300 Bloom, Porcine GelMA 175 Bloom, Bovine GelMA 225 Bloom, Fish GelMA warm water, and Fish GelMA cold water. Up to three can be combined in a single formulation.
The combined concentration across all bases is capped at 20% (w/v). Each base is set in 5% steps, so a single blend can run 5, 10, 15, or 20% (w/v) in total.
LAP, or lithium phenyl-2,4,6-trimethylbenzoylphosphinate, at 0.25, 0.5, 1, 1.5, or 2% (w/v). LAP crosslinks under 365 nm and 405 nm light, which covers most DLP and extrusion photocuring setups.
A ready-to-use custom blend is $550 for 50 ml, $2,000 for 200 ml, and $4,500 for 500 ml. The optional HAMA add-on adds $75, $250, or $500 respectively. Final pricing is confirmed on the quote.
Every blend you configure produces a short code that captures the full recipe. You can copy it, reload it later to rebuild the same formulation, or share it as a link so a colleague opens the mixer with your exact blend already set.
There is no standing free sample program for custom bioinks, though we do consider requests case by case, so ask if a sample would help. The complimentary 5 g first-order sample applies to catalog GelMA, which is a useful way to evaluate a base material before ordering a custom formulation.
As a ready-to-use liquid formulation, shipped at ambient temperature with no cold chain required. Add the Anti-Anti antibiotic-antimycotic option if your cultures run long enough to need contamination control.
