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-G3 (Human) is a thermostabilised recombinant growth factor designed to replace conventional wild-type FGF2 in cell culture. It supports efficient proliferation and maintenance of stem and progenitor cells across a range of mammalian species relevant to cultivated-meat production. By maintaining full biological activity for over three weeks at 37 °C, FGF2-G3 enables consistent culture performance with minimal media changes, reducing both cost and labour in growth-factor-dependent workflows.
The FGF2-G3 sequence differs from canonical human FGF2 at nine amino-acid positions, enhancing protein stability and activity under physiological conditions. It exhibits an ED₅₀ below 1 ng/mL, confirming high potency in proliferation assays, and is typically required at less than half the concentration of wild-type FGF2 in media formulations such as HiDef B8. Produced recombinantly in E. coli and purified to greater than 95 % by SDS-PAGE, FGF2-G3 is supplied as either a sterile 1 mg/mL liquid or lyophilised powder for flexible downstream use.
Its prolonged half-life eliminates the need for weekend supplementation and daily media replacement, enabling more stable and homogeneous cell populations. FGF2-G3 integrates directly into serum-free or chemically defined media for cultivated-meat research and pilot production.
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...
