Hu Recom IFN-beta, 25 µg

Recombinant human interferon-beta is a type I interferon cytokine widely used in immunology and cell biology research. This lyophilized preparation from STEMCELL Technologies supports reproducible stimulation of innate immune signaling in vitro, including JAK/STAT pathway activation, MHC class I upregulation, and induction of interferon-stimulated genes. Researchers commonly use it to differentiate monocytes into dendritic cells, model antiviral responses, and supplement serum-free or defined culture media at typical working concentrations of 1–100 ng/mL. The 25 µg format is supplied as a single vial suitable for routine batch stimulation of cell lines or primary leukocytes. After reconstitution in sterile water or PBS, store aliquots frozen at -20°C to -80°C, protecting from freeze-thaw cycles to preserve bioactivity. Each lot is verified for biological activity consistent with reference standards, ensuring consistent performance in antiviral cytopathic effect assays, western blot analysis of STAT phosphorylation, and gene expression studies of interferon-stimulated genes. Suitable for research use only in academic and biopharmaceutical laboratories focused on cytokine signaling, viral immunity, and inflammation.
