HumanKine® recombinant cytokines & growth factors are produced at Proteintech’s GMP facility near Chicago, meaning complete control over the quality, scalability, and lot-to-lot consistency of the products. They are expressed in a proprietary HEK293 (human) expression system, for high activity and purity authentic human proteins with native glycosylation and folding. In addition, Proteintech has the largest portfolio of self-manufactured antibodies covering 2/3 of the human proteome and has acquired ChromoTek, a leader in Nanobody-based reagents.

  • HumanKine® Cytokines and Growth Factors
    Human-cell expressed cytokines and growth factors for high bioactivity, stability and native human conformation & post-translational modifications. We offer these both for research grade and GMP grade....

  • HumanKine® recombinant proteins are created in HEK293 cells using animal free components

    Proteins co-expressed in bacteria will not possess post-translational modifications, e.g., phosphorylations or glycosylation. For activity, many proteins require gylcosylation and processing available exclusively in eukaryotic systems; specifically human systems for authentic human proteins. 

    All HumanKine recombinant proteins are produced in Proteintech's in-house cGMP grade laboratory (ISO13485) adhering to strict quality control regulations.
