Recombinant Human FGF-2 (145aa)
High-purity recombinant human FGF-2 produced in E. coli. animal-origin free, endotoxin-controlled and validated for robust activity in stem-cell applications.
Recombinant Human FGF-2 (145 aa) also known as basic fibroblast growth factor (bFGF), is a high-purity, carrier-free growth factor produced in E. coli and designed to deliver robust, reproducible activity in advanced stem–cell research workflows. Corresponding to the 145-aa core region of human fibroblast growth factor 2, this form actively supports the expansion and maintenance of induced pluripotent stem cells (iPSCs), embryonic stem cells (ESCs), mesenchymal stem cells (MSCs), and a broad range of proliferation and differentiation models.
Its animal-origin–free composition and stringent control of endotoxin levels ensure consistent biological performance in sensitive cell-culture systems. Supplied as a stabilized lyophilized powder, the protein enables easy reconstitution, high recovery, and lot-to-lot consistency, making it ideal for demanding research workflows.
A GMP-grade version of the Recombinant Human FGF-2 (145 aa) suitable for therapeutic manufacturing is also available upon request. Contact us.

FAQs
Why is FGF-2 a key growth factor in stem-cell expansion workflows?
Recombinant human FGF-2, also known as basic fibroblast growth factor (bFGF), plays a central role in the expansion and maintenance of pluripotent and mesenchymal stem cells, supporting controlled proliferation while preserving key cellular characteristics. These properties make FGF-2 widely used not only in basic research, but also in process development and preclinical workflows related to cell therapy and regenerative medicine.
In which advanced applications is FGF-2 commonly applied?
FGF-2 is widely used in stem-cell expansion, angiogenesis-related models and proliferation-driven culture systems. It is frequently included in development-stage workflows supporting regenerative medicine, tissue engineering and cell-based therapeutic research.
Martin Keller –
We have been using this growth factor routinely in fibroblast and stem cell culture workflows. The reconstitution protocol was straightforward and the performance between experiments has been consistent, which is important for long culture schedules. It integrated easily into our standard media preparation workflow.
Aiko Tanaka –
We tested this growth factor in stem cell maintenance work in our company. Reconstitution and incorporation into the media routine were straightforward, and batch-to-batch use has been smooth so far. It has become one of the products we reorder.
