GMP Quality Policy and Regulatory Support

GMP Protein Quality Policy

R&D Systems provides industry-leading quality and regulatory support for GMP ancillary and raw materials, including recombinant cytokines and growth factors, used in ex vivo cell therapy manufacturing. Using our experienced quality and manufacturing teams, our goal is to provide cell therapy manufacturers with a consistent, safe, and continuous supply of GMP-grade raw materials.

Patient safety is of utmost importance. R&D Systems® GMP proteins undergo a battery of physical tests as well as assessments for adventitious agents and contaminants. We use preferred vendors for raw materials to mitigate risk and adhere to a strict definition of animal-free. Certificates of Origin (COOs) are available upon request.

Consistency Supported by Documentation and Traceability:

  • Individual specification sheets with all testing results are reviewed by both our Quality Control (QC) and Quality Assurance (QA) departments
  • A full QA review of all batch and bottling records before any material is shipped
  • Documented processes and QA control of documentation and process changes
  • Personnel training programs
  • Raw material testing, tracing, and vendor qualification/monitoring
  • Fully validated equipment, processes, and test methods
  • Equipment calibration schedules using a computerized calibration program
  • Facility maintenance and safety programs
  • Material review board for variances
  • Monitoring of stability over product shelf life
  • Product change notifications


To ensure a consistent product, extraordinary attention to detail is needed at all levels of the protein manufacturing process. The quality management systems for GMP proteins at R&D Systems include detailed Standard Operating Procedures (SOPs) and quality-controlled documentation of the manufacturing equipment and procedures. These industry-leading systems, including the bulleted items below, are why our GMP proteins can be relied on for cell therapy manufacturing.

Quality Control Testing Includes:

  • Biological potency specification
  • Defined Purity Specifications
  • Stability testing program
  • Defined endotoxin specifications
  • Host cell content testing
  • Sterility testing according to USP
  • Viral testing of eukaryotic cell banks and viral reduction studies - Contact us for details
  • More testing available depending on your needs

Supply Chain Continuity

We understand the critical nature of having a stable supply of GMP-grade proteins for use as raw materials in ex vivo cell manufacturing. This becomes progressively more important during the transition from early- to late-stage clinical trials.

We have the expertise and ability to scale up your GMP protein supply. Working with your forecasting, we will provide supply and quality agreements to ensure the consistent supply of the GMP proteins you require.

Our Stable Supply Process Includes:

  • Supply and quality agreements
  • Risk mitigation management
  • Secondary cell banking facility
  • Quality-controlled change and notification process

Animal-free Manufacturing

To support developing research and bioproduction demands, we have quality-controlled manufacturing space dedicated to the production and purification of recombinant proteins under completely animal-free conditions.

For more detailed information, please visit our Animal-free Recombinant Proteins page


Production and purification procedures use equipment and media that are certified animal-free. Our dedicated controlled-access animal-free laboratories ensure that at no point in production are these products exposed to potential contamination by animal components or byproducts. Some GMP proteins are manufactured under an animal-free process.
