CTGrade rh IL-3 is a recombinant human protein that is produced from E. coli and is designed to support basic, translational, and clinical research, as well as commercial applications, and offers:
- High biological activity verified by a relevant bioactivity assay
- Low endotoxin levels
- ≥ 97% purity
- High lot-to-lot consistency
Size: 50 µg, 100 µg, and 1 mg. Custom sizes and packaging available on request.
IL-3 is a species-specific cytokine and pleiotropic growth factor that promotes the survival, differentiation, and proliferation of committed progenitor cells of the megakaryocyte, granulocyte-macrophage, erythroid, eosinophil, basophil, and mast cell lineages.
- Produced by T cells, mast cells, and eosinophils, IL-3 enhances thrombopoiesis, phagocytosis, and antibody-mediated cellular cytotoxicity
- Its ability to activate monocytes suggests that IL-3 may have additional immunoregulatory roles
- Many of the IL-3 activities depend upon co-stimulation with other cytokines
The biological activity of CTGrade interleukins and growth factors is standardized, where applicable, to WHO International standards, providing cell and gene therapy developers consistent, lot-to-lot biological activity and performance.
The CTGrade products are manufactured in a facility that does not use or process beta lactam containing materials. No animal- or human-derived materials were used during manufacturing or as ingredients. These products are manufactured, tested, and released in an ISO 9001:2015 certified facility following cGMP practices. USP chapter <1043> for ancillary materials has been considered in the manufacture of these products.
*For research use or further manufacturing and in ex vivo cell therapy applications.
**Animal component-free to the tertiary level (no animal-origin components or sub-components are used in the product, raw materials, including packaging or the manufacturing process). Supporting documentation available upon request.
***Lot-specific values for the following specifications are supplied with each product on its corresponding COA. The values provided here are minimum expected values to pass internal requirements.
