This 146 amino acid variant is a potent mitogen that stimulates the proliferation of cells of mesodermal and neuroectodermal origin. It is a critical component in media formulations for pluripotent stem cells (PSCs), neural stem cells, and endothelial cells, playing a vital role in maintaining pluripotency and directing lineage-specific differentiation.\u003c\/p\u003e\n\n\u003cp\u003eThis growth factor is expressed in E. coli and purified to exceptional standards, typically exceeding 95% purity as determined by SDS-PAGE and visualized by silver stain. Each lot is rigorously validated for biological activity using a cell proliferation assay with Quiescent NR6R-3T3 fibroblasts, ensuring an ED50 typically within 0.1–0.6 ng\/mL. The lyophilized formulation is carrier-free, providing researchers with a clean, high-performance reagent for sensitive applications in regenerative medicine and cancer research.\u003c\/p\u003e\n\n\u003cp\u003eThe 146 aa FGF-basic is ideal for both foundational research and advanced bioprocessing where precise control over cell signaling is required. Known for its robust performance across multiple cell types, it is a dependable choice for wound healing studies, angiogenesis assays, and stem cell expansion. For maximum stability, the protein should be reconstituted according to validated protocols and stored in working aliquots at -20°C to -70°C to avoid repeated freeze-thaw cycles.\u003c\/p\u003e","brand":"R\u0026D Systems","offers":[{"title":"10 µg","offer_id":52815649800520,"sku":"233-FB-010","price":107.0,"currency_code":"GBP","in_stock":true},{"title":"25 µg","offer_id":52815649866056,"sku":"233-FB-025","price":214.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0906\/7570\/8232\/files\/Screenshot_2026-03-12_at_12.44.26_AM_c317190e-ef3b-4082-8a23-0f7791b69be2.png?v=1773257264","url":"https:\/\/cellbase.com\/products\/r-d-systems-recombinant-human-fgf-basic-fgf2-bfgf-146-aa-protein-w-carrier","provider":"Cellbase","version":"1.0","type":"link"}
