Worlds First Cultivated Meat B2B Marketplace: Read Announcement
In stock. Ships globally direct from Defined Bioscience to research and production facilities.
Add to cart & view shipping options / prices in checkout for your region. Orders fulfilled directly by Defined Bioscience with temperature-controlled shipping where required.
Purchase orders also accepted. Select bank transfer at checkout and provide your PO number in order notes or email to sales@cellbase.com
Suppliers invoice directly. VAT handled per vendor jurisdiction.
Card payments process immediately. Bank transfer and PO orders process upon payment receipt.
Most products require no additional agreements. Cell lines and certain biological materials require a Material Transfer Agreement (MTA) on first purchase from each supplier. We handle this digitally - both parties sign online before shipment. Subsequent orders from the same supplier proceed immediately.
Defined Bioscience provides direct post-sales support including troubleshooting, process optimisation, and protocol guidance. Batch-specific documents available on request.
Defined Bioscience’s FGF2 (Tuna) is a recombinant, animal-origin-free fibroblast growth factor 2 derived from Thunnus albacares (yellowfin tuna). It supports cell proliferation, differentiation, and maintenance in serum-free and chemically defined media, particularly for marine and aquatic cell lines used in cultivated-seafood research. As a native fish homolog, it enhances compatibility with piscine cells while maintaining cross-species functionality across mammalian and avian models.
Produced recombinantly in E. coli, FGF2 (Tuna) is supplied carrier-free and purified to greater than 95 % by SDS-PAGE, ensuring consistent purity and performance. The protein contains an N-terminal hexahistidine tag and protease cleavage site and is formulated in phosphate buffer at 1 mg/mL. Biological activity testing demonstrates an EC₅₀ below 2 ng/mL in NIH-3T3 proliferation assays, confirming high potency at low concentrations.
The recombinant production process is fully animal-component-free and supports reproducible performance across long-term culture conditions. FGF2 (Tuna) can be incorporated directly into basal or serum-free media formulations to improve cell viability and proliferation in fish cell lines, aiding optimisation of cultivated-seafood workflows from R&D through to pilot-scale studies.
For research and development use only. Not for human or diagnostic applications.

Today we're launching Cellbase. It's a B2B marketplace built for one purpose: making it easier for cultivated meat companies to source what they need to grow. No hype. No grand...
When producing cultivated meat, choosing between reusable and single-use bioprocessing systems is a key decision. Each option has distinct advantages and challenges, particularly around cost, scalability, and resource use. Here's...
Scaffolds are critical in producing cultivated meat, providing a 3D framework for cells to grow into structured, meat-like tissues. The choice of biomaterial affects everything from texture and mouthfeel to...
When choosing a bioreactor for cultivated meat production, single-use systems and reusable systems each offer distinct cost advantages and challenges. Here's the key takeaway: Single-Use Bioreactors: Lower upfront costs (50–66%...
Precision Monitoring & Regulation: Automated systems maintain optimal conditions (e.g., temperature, pH, dissolved oxygen) in bioreactors, ensuring consistent cell growth and reducing batch failures. Cost Efficiency: Automation optimises resource use,...
Cultivated meat production is expensive, with growth media alone making up 55–95% of costs. Reducing these costs requires smarter sourcing strategies. UK producers face a key decision: buy from local...
Choosing between single-use and reusable systems for cultivated meat production depends heavily on production scale and financial priorities. Here's a quick breakdown: Single-use systems: Lower upfront costs (50–66% less than...
Maintaining a stable pH is critical for cultivated meat production, as mammalian cells require a narrow pH range of 7.4 ± 0.4 to grow effectively. Even minor pH fluctuations can...
