Animal-free Cytokines & Growth Factors

In addition to its wide range of recombinant cytokines, growth factors, receptors and CD markers from human, mouse and rat, PromoKine now also offers a selection of recombinant cytokines and growth factors that have been produced plants (barley seed endosperm or tobacco) at high isogenic quality.

  • No proteolytic, pyrogenic, or inflammatory activity
  • Free of bacterial, viral and prion infectious agents as well as contaminating molecules such as endotoxins (bacterial expression host) or cytokines, chemokines and growth factors (mammalian expression host)
  • No serum carryover that may cause unwanted effects (such as proliferation)
  • Proper eukaryotic folding and post-translational modification (e.g. glycosylation) that increases biological activity and stability  
  • More than 20 cytokines and growth factors available (e.g. Activin A, BAFF, BMP-2, BMP-7, EGF, FGF-2, Flt3-Ligand, GM-CSF, LIF, M-CSF, Myosatin, diverse Interleukins, IFN-alpha, IFN-gamma, TGF-beta, TNF-alpha, VEGF)
