Announcing Our New State-of-the-Art GMP Protein Manufacturing Facility
We're committed to meeting the increasing demands of therapeutic cell manufacturing. Our facility supports large-scale production of GMP-grade materials including E. coli-derived recombinant proteins.
Ensure High Bioactivity, Consistency, and Purity in GMP Cytokines
The use of high quality growth factors and cytokines is paramount to ensuring safety, bioactivity, and minimal batch-to-batch variability. We ensure lot-to-lot consistency in both purity and bioactivity with our robust quality management system. Greater cytokine and growth factor potency also lowers the amount of protein needed and helps to reduce manufacturing costs.

Analysis of the Activity, Lot-to-Lot Consistency, and Purity of GMP-grade Recombinant Human IL-2
(A) Three independent lots of GMP-grade Recombinant Human IL-2 (R&D Systems, Catalog # BT-002-GMP) were tested for their ability to stimulate proliferation of CTLL-2 mouse cytotoxic T cells. The ED50 for this effect is 0.03-0.25 ng/mL. Each trace on the graph represents data obtained from GMP-grade Recombinant Human IL-2 from a different manufacturing run, demonstrating the lot-to-lot consistency of the protein. (B, C) The purity of the three independent lots of GMP-grade Recombinant Human IL-2 shown in part A were assessed by CE-SDS on Maurice (ProteinSimple, Catalog # 090-000) under reducing (R; part B) and non-reducing (NR; part C) conditions and visualized in Compass for iCE software. The gel views obtained from the Compass software are shown.

Analysis of the Activity, Lot-to-Lot Consistency, and Purity of GMP-grade Recombinant Human IL-7
(A) Three independent lots of GMP-grade Recombinant Human IL-7 (R&D Systems, Catalog # BT-007-GMP) were tested for their ability to stimulate proliferation of PHA-activated human peripheral blood lymphocytes. The ED50 for this effect is 0.1-0.5 ng/mL. Each trace on the graph represents data obtained from GMP-grade Recombinant Human IL-7 from a different manufacturing run, demonstrating the lot-to-lot consistency of the protein. (B, C) The purity of the three independent lots of GMP-grade Recombinant Human IL-7 shown in part A were assessed by CE-SDS on Maurice (ProteinSimple, Catalog # 090-000) under reducing (R; part B) and non-reducing (NR; part C) conditions and visualized in Compass for iCE software. The gel views obtained from the Compass software are shown. The IS band is a 10 kDa Maurice CE-SDS Internal Standard Marker (ProteinSimple, Catalog # 046-144) that was added to each sample to calculate the relative migration time (RMT).

(A) Three independent lots of GMP-grade Recombinant Human IL-10 (R&D Systems, Catalog # 1064-GMP) were tested for their ability to stimulate proliferation of MC/9-2 mouse mast cells. The ED50 for this effect is 0.0750-0.750 ng/mL. Each trace on the graph represents data obtained from GMP-grade Recombinant Human IL-10 from a different manufacturing run, demonstrating the lot-to-lot consistency of the protein. (B, C) The purity of the three independent lots of GMP-grade Recombinant Human IL-10 shown in part A were assessed by CE-SDS on Maurice (ProteinSimple, Catalog # 090-000) under reducing (R; part B) and non-reducing (NR; part C) conditions and visualized in Compass for iCE software. The gel views obtained from the Compass software are shown. The IS band is a 10 kDa Maurice CE-SDS Internal Standard Marker (ProteinSimple, Catalog # 046-144) that was added to each sample to calculate the relative migration time (RMT).

What is an Animal-Free Protein?
Manufacturing procedures for these proteins utilize equipment and reagents 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.

Supply Chain Continuity
It is critical to secure 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 process forecasting, we will provide supply and quality agreements to ensure the consistent supply of the GMP proteins you require.
- Risk mitigation management
- Secondary cell banking facility
- Quality-controlled change and notification process

Cytokine Supplier Webinar
In this 15-minute webinar, you will learn how effective partnering is central to ensuring end-users' primary considerations of patient safety, lot-to-lot consistency, and supply chain reliability, including tips for choosing your next supplier:
