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 GMP 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 GMP 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.

Shelf life: Unopened vials are stable for 36 months from the date of manufacture as indicated on the label. Reconstituted material should be apportioned in working volumes and stored at or below –20 °C in manual defrost freezer. For short term storage reconstituted material is stable for four to six weeks when stored at 2 to 8 °C. Stability can be increased by adding at least 0.1% carrier protein.
