CellGenix® rh IL-1β
GMP and Preclinical grade
CellGenix Recombinant Human IL-1β reliably stimulates the maturation of immature dendritic cells (DCs). It in addition promotes the generation of megakaryocytes derived from pluripotent stem cells (PSCs). CellGenix rh IL-1β is produced in our dedicated animal-free facility ensuring maximum safety for optimal use in ATMP manufacturing.
General Information
Interleukin-1 beta (IL-1β) is a proinflammatory cytokine that is mainly produced by monocytes and activated macrophages as a proprotein. Inflammatory responses are mediated by IL-1β in T cells, natural killer cells (NK cells) and B cells. It induces the production of pro-inflammatory cytokines (IL-2, IL-3, IL-6) as well as interferons. Furthermore, IL-1β modulates the secretion of cytokines by various subsets of human DCs.
CellGenix IL-1β is used in the cell and gene therapy space for the ex vivo maturation of immature DCs.
GMP Grade
CellGenix GMP Recombinant Human IL-1β is produced following all applicable GMP guidelines and allows for the safe use in accordance with USP Chapter <1043> and Ph. Eur. General Chapter 5.2.12.
Our GMP cytokines are provided with documented evidence of purity, potency, consistency and stability. In combination with our expert regulatory and technical support this will help simplify your raw material qualification and validation efforts.
