GMP manufacturing process

Proteintech cGMP manufacturing process diagram


To facilitate a seamless preclinical to clinical transition, we offer both RUO and GMP grade cytokines and growth factors. Both product grades are produced under the same conditions in a GMP facility, using identical production processes. The GMP grade products come with extensive documentation, as well as thorough QC testing and traceability, whereas our line of RUO grade products are more cost-effective during early research and development.

Animal component and Xeno free

Driven by the desire for improved product consistency and safety of our products, we follow a strict Animal component-free (ACF) and Xeno-free policy. This policy ensures:

  • The final product does not contain any constituent that is either an animal tissue, body fluid or components derived from it.
  • All the materials, from procurement to final products, are stored and handled in a dedicated animal-free facility.
  • The final product do not contain materials from non- human animal sources or recombinant materials made from non-human animal sources.

GMP Lot-to-lot Consistency

Consistency in raw material features is critical for efficient manufacturing of cell based therapies. A well-defined manufacturing process of HumanKine growth factors ensures high lot -to-lot consistency in its identity, purity and bioactivity.

GMP BMP-4 (HZ-1045-GMP)

Three independent lots of GMP BMP-4 were tested for their ability to induce alkaline phosphatase production in ATDC5 (mouse chondrogenic) cells

Figure 1: Three independent lots of GMP BMP-4 were tested for their ability to induce alkaline phosphatase production in ATDC5 (mouse chondrogenic) cells. The EC50 for this assay is 1.5-9 ng/mL. The activity of each lot is nearly identical. Each lot was also analyzed for purity on an SDS-polyacrylamide gel under reducing and non-reducing conditions.

GMP PDGFbb (HZ-1308-GMP)

Three independent lots of GMP PDGFbb were tested for their ability to induce the proliferation of NIH/3T3 (mouse fibroblasts) cells.

Figure 2: Three independent lots of GMP PDGFbb were tested for their ability to induce the proliferation of NIH/3T3 (mouse fibroblasts) cells. The EC50 for this assay is 0.3-3.0 ng/mL. The activity of each lot is nearly identical. Each lot was also analyzed for purity on an SDS-polyacrylamide gel. This data demonstrates the lot-to-lot consistency of this protein.


  1. How are HumanKine GMP cytokines different from the RUO cytokines?

GMP proteins come with extensive documentation for traceability, as well as additional quality control testing and quality assurance reviews, whereas the RUO grade line offers reliable products which are more cost-effective during early research and development. As the manufacturing process is the same for RUO and GMP products, HumanKine offers a seamless preclinical-to-clinical transition line of products, saving a significant amount of time and money.


  1. Are HumanKine GMP cytokines suitable for direct human administration?

No, HumanKine GMP products are not intended to use as an excipient or therapeutic product that can be directly administered to the human body. These products are developed to be used as raw materials for the manufacturing of cell and gene therapy products, but not as part of the final formulation or therapy.


  1. Is HumanKine GMP product manufacturing certified by FDA or other regulatory agencies?

US-FDA does not audit or certify manufacturing facilities that produce ancillary materials. HumanKine GMP products are manufactured under the ISO13485 quality management system adhering to USP and European pharmacopeia recommendations to ensure potency, purity, and safety. The manufacturing facility can be audited by the end users upon request.


  1. What is the risk classification for HumanKine GMP Cytokines?

HumanKine GMP Cytokines are classified as Tier 2 risk products under USP Chapter <1043>. The products are low-risk, well-characterized materials, produced in compliance with GMP guidelines, and intended to be used as ancillary materials/raw materials.


  1. Are HumanKine GMP cytokines animal component free?

Yes! HumanKine GMP manufacturing processes and the final product do not use or contain any animal or human-derived components.


  1. How are HumanKine GMP cytokines shipped?

HumanKine GMP products are shipped as lyophilized, in glass vials at ambient temperature. The stability of these products is extensively tested to ensure the above-specified shipping conditions do not affect product quality or performance.
