Hu Recom FGF-acidic, ACF, 100 µg

A purified, animal component-free human recombinant growth factor from STEMCELL Technologies drives FGF-acidic (FGF-1) signaling in defined cell culture systems. This 100 µg vial supports maintenance and expansion of embryonic stem cells, induced pluripotent stem cells, neural progenitors, and mesenchymal stromal cells across feeder-free workflows.

FGF-acidic activity promotes proliferation, migration, and survival through FGFR receptor engagement on responsive lineages. Working concentrations typically range from 5 to 100 ng/mL depending on cell type. The lyophilized format should be reconstituted in sterile 10 mM Tris pH 7.6 or PBS supplemented with 0.1% BSA, then stored frozen at -20 °C or -80 °C in single-use aliquots to preserve activity through multiple freeze-thaw cycles.

Each lot is verified by proliferation-based bioactivity assays and QC-tested for purity, endotoxin, and mycoplasma. Because the ACF manufacturing process eliminates exposure to animal-derived raw materials, this reagent is well suited for translational and clinical-grade pipelines that demand full traceability of culture inputs.
