Superior quality recombinant proteins are key to assuring the performance and commercial success of advanced therapies. Proteintech's GMP-grade and Research-grade HumanKine® recombinant proteins are well validated and proven to be stable, safe, pure and potent.

All HumanKine® recombinant proteins  are generated in HEK293 cells. The use of human expression system guarantees that the HumanKine® proteins have native conformation and post translational modifications which ensures the optimum activity of the protein. These proteins are expressed and purified without any tags.

Benefits of HumanKine® recombinant proteins

Recombinant proteins are proteins encoded by a gene - recombinant DNA - that has previously been cloned in a system that supports the gene expression and translation of messenger RNA.

Proteins coexpressed in bacteria will not possess post-translational modifications, e.g., phosphorylation or glycosylation. For activity, many proteins require glycosylation and processing only available in eukaryotic systems. Human stem cell technology and CAR-T cell therapy also require culture media whose components must be animal component and xenobiotic free.

HumanKine® recombinant proteins are created in HEK293 cells using animal-free components. Our human expression system ensures that proteins have native conformation and post-translational modifications to optimize biological activity. No expression tags, xeno-free…just high quality proteins.
