Available GMP Proteins
Lot-to-Lot Consistency
As you scale your clinical manufacturing process, it often becomes necessary to use GMP cytokines and growth factors from different lots. Through decades of manufacturing expertise, R&D Systems had developed a mature quality management system with detailed protocols, creating recombinant proteins with industry-leading consistency. Each new lot is tested against a master lot and must pass stringent quality control specifications for activity in a well-defined bioassay.
Three independent lots of GMP IL-2 (A, Catalog # BT-002-GMP), IL-7 (B, Catalog # BT-007-GMP), and IL-10 (C, Catalog # 1064-GMP) were tested for their ability to stimulate proliferation of CTLL-2 mouse cytotoxic T cells, PHA-activated human peripheral blood lymphocytes, and MC/9-2 mast cells, respectively. Each trace on the graphs represents data obtained from a different manufacturing run, demonstrating the lot-to-lot consistency of each protein.
Grade-to-Grade Consistency
Not only are the proteins consistent lot-to-lot, but also across RUO, animal-free, and GMP grades. Both animal-free RUO and GMP grades of E. coli sourced proteins share the same sequence, source, formulation, activity and purity specifications, manufacturing site and personnel, and vial type – ensuring equivalent performance and process continuity as you transition to the clinic.
The three grades of IL-2 (A, Catalog # BT-002, BT-002-AFL, and BT-002-GMP), IL-4 (B, Catalog # BT-004, BT-004-AFL, and BT-004-GMP), and BDNF (C, Catalog # BT-BDNF, BT-BDNF-AFL, and BT-BDNF-GMP) were tested for their ability to stimulate proliferation of CTLL-2 mouse cytotoxic T cells, TF-1 human erythroleukemic cells, and BaF mouse pro-B cells transfected with TrkB, respectively. All grades show equivalent bioactivity, enabling a seamless transition as higher levels of regulation and documentation are needed.
GMP Quality Policy and Regulatory Support
GMP-grade cytokines and growth factors are produced under regulatory guidelines for ancillary materials in cell therapy manufacturing processes. This includes extensive quality control testing and comprehensive documentation of manufacturing systems and traceability of source materials. You can be confident you will receive a consistent, safe, and traceable supply of raw materials. We perform regular audits of our facilities and welcome customer audits.
