> Key Raw Materials for Cell and Gene Therapy 
ACROBiosystems offers a wide range of raw materials and tools needed for cell therapy products, including cytokines, nucleases, and activation beads. We provide several grades of materials, including both premium and GMP grades. Our premium grade proteins originate from the same clone, sequence, and expression system as our GMP products. This means developers utilizing our premium-grade products can be easily transition into GMP products for use in CMC or clinical stages without more comparability studies of the manufacturing process.
To facilitate the transition of your cell therapy product into clinical trials and beyond, developing a raw material strategy that considers the end goal is critical. For early-stage research and development of cell therapy, research-use only (RUO) materials are most commonly used. However, as the development progresses into the preclinical or clinical phases, RUO materials that may have been sufficient before do not meet the criteria required to proceed. Most strategies emphasize the use of the highest grades of raw materials available as early as possible; however, this may not always be feasible. Accounting for material grade transitions can help balance both performance and costs when moving onto the next stage.
ACROBiosystems offers several different grades of materials for different development stages in your cell therapy product. Premium grade materials are produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. GMP grade materials are developed using our GMP-grade quality management system platform. These products are produced with strict quality management and drug-level release testing standards. Since our premium grade components are similar to our GMP products, the transition between grades can be easily performed without further comparability studies.

Recombinant Human IL-15 Protein premium grade (IL5-H4117), designed for preclinical stage, has the same activity and performance with GMP Grade IL-15 (GMP-L15H13), which enables a seamless transition from preclinical development to clinical phases .
Human IL-7 Protein premium grade (IL7-H4219) designed for preclinical stage, has the same activity and performance with GMP Grade IL-7 (GMP-L07H24), which enables a seamless transition from preclinical development to clinical phases .
Bioactivity of three different lots of GMP Human IL-15 (GMP-L15H13) verified by cell-based assay, and the result shows very high batch-to-batch consistency.
The Cell based assay shows that GMP Human IL-7 (GMP-L07H24) is stable at 37°C for 48 hours and after freezing and thawing 3 times.
