Recombinant proteins

Curated cytokine, checkpoint, growth-factor and TNF-superfamily shortcuts from Puweituo Bio—each opens a filtered catalog lane you can pair with target and application hubs.

• Cytokines

  Secreted cytokines—interleukins, TNFs, IFNs and chemokines—for immune stimulation, stem-cell and tumor microenvironment models.

• Immune checkpoints

  Checkpoint-target recombinant proteins and ECD constructs for tumor immune escape biology and assay development.

• Growth factors

  Mitogenic GF families—FGF, EGF, HGF and VEGF—for organoid cultures, stem-cell expansion and feeder-free maintenance.

• TNF / receptor superfamily

  TNF superfamily ligands and decoy receptors to study apoptotic signaling, costimulation and innate immune crosstalk.

• Interleukins

  IL-2 / IL-6 / IL-10 / IL-12 series supporting T-helper polarization and inflammatory cytokine profiling.

• Interferons

  Type I and II interferon proteins for innate antiviral responses and immuno-oncology synergy studies.

• Organoids & iPSC cytokines

  RSPO, Activin, HGF and peers for organoid expansion—pairs with cytokine categories and custom media programs.

• Infectious disease antigens

  Receptor ECDs and viral antigen scaffolds enabling respiratory and pan-strain vaccine immunogenicity studies.
