Recombinant Human FGF-2 TOP® GMP
FGF-2 TOP GMP is a thermostabilized, recombinant human growth factor manufactured in a novel plant-based expression system that provides a cost-effective, GMP-quality solution for the growth of stem cells and adherent HEK cells.
The FGF-2 TOP® GMP Advantage
Plant-Based and Sustainable
Significant Cost Savings
Scale at GMP Quality
A Convenient Alternative with Cost Advantages
In order to maintain pluripotency and avoid spontaneous differentiation of stem cells, scientists traditionally had to maintain a strict daily feeding schedule due to the short half-life (approximately 9 hours at 37°C) and temperature sensitivity of wild-type FGF-2.
10-Fold Improvements in Half-Life at 37°C
To improve stability, a novel nine amino acid substitution of the wild-type FGF-2 was performed, improving the heat stability of FGF-2 TOP resulting in an increase in half-life under cell culture conditions to 37°C.
Supplement Less and Achieve More Consistency
By nature of its increased half-life and stability, FGF-2 TOP presents a constant exposure of growth factor (green line) in contrast to the short half-life and signaling of the wild-type protein that must be replenished daily (yellow line). Thus, feeding schedules are more streamlined and cell culture phenotype is more homogenous.
The Stability to Support Your Development and Scale-Up
Preservation of Bioactivity
Supporting Proliferation of Adherent Cell Culture
In an internal MSC model analyzing confluence over 9 days, the addition of FGF-2 TOP to an internal MSC formulation resulted in an equivalent cell confluence and expansion (as assessed through cell attachment) compared to the positive control containing 10% FBS. Similar results have been observed in both iPSC and adherent HEK-293 models (assessed but not shown).

How is the quality control for Core Biogenesis plant-derived growth factors?
Core Biogenesis offers its customers effective, pure, and safe products. They carry out rigorous analysis of their products, including purity assessment to assure customers high-quality products. Growth factors are tested for biological activity by independent third-party companies or laboratories, and this information is provided in a data sheet for each batch of every product.
For how long are Core Biogenesis growth factors stable?
The QC testing backing our products has assessed to date, full performance and maintenance of the stated bioactivity for up to 6 months since product release. Core Biogenesis is currently determining the full shelf-life of our products before and after reconstitution for up to 2 years. Core Biogenesis believes in total transparency about their products and data.
