Scientific Data Examples for ProDots Recombinant Human IL-15 GMP Protein

	5 µg of GMP Human IL-15 as one spheroid of 5 µg inside a sterile bag with a needless valve port and weldable tube port. GMP-grade ProDots^®Recombinant Human IL-15 (Catalog # PRD247-GMP) stimulates cell proliferation of MO7e human megakaryocytic leukemic cells. Three independent lots were tested for activity and plotted on the same graph to show lot-to-lot consistency of GMP ProDots IL-15.
	Equivalent bioactivity of GMP ProDot™ Proteins to GMP Proteins. Comparative tests for function within biologically relevant model systems show equivalence of GMP ProDot™ Proteins and GMP Proteins. Activation of PBMCs after 9 days in culture with ExCellerate Human T Cell Media CCM030, GMP Cloudz Human T Cell Activation Kit CLD001-GMP and GMP IL-15 ProDot PRD247-GMP or GMP IL-15 247-GMP shows comparable A. T cell fold expansion and B. phenotypes

Background: IL-15

Interleukin 15 (IL-15) is a widely expressed 14 kDa cytokine that is structurally and functionally related to IL-2 and plays an important role in many immunological diseases (1, 2). Mature human IL-15 shares 70% amino acid sequence identity with mouse and rat IL-15. Alternative splicing generates isoforms of IL-15 with either a long or short signal peptide (LSP or SSP), and the SSP isoform is retained intracellularly (3). IL-15 binds with high affinity to IL-15 R alpha (4). It binds with lower affinity to a complex of IL-2 R beta and the common gamma chain ( gamma c) which are also subunits of the IL-2 receptor complex (5). IL-15 associates with IL-15 R alpha in the endoplasmic reticulum, and this complex is expressed on the cell surface (6). The dominant mechanism of IL-15 action is known as transpresentation in which IL-15 and IL-15 R alpha are coordinately expressed on the surface of one cell and interact with complexes of IL-2 R beta / gamma c on adjacent cells (7). This enables cells to respond to IL-15 even if they do not express IL-15 R alpha (6). In human and mouse, soluble IL-15-binding forms of IL-15 R alpha can be generated by proteolytic shedding and bind up nearly all the IL-15 in circulation (8-10). Soluble IL-15 R alpha functions as an inhibitor that limits IL-15 action (4, 9). Ligation of membrane-associated IL-15/IL-15 R alpha complexes also induces reverse signaling that promotes activation of the IL-15/IL-15 R alpha expressing cells (11). IL-15 induces or enhances the differentiation, maintenance, or activation of multiple T cell subsets including NK, NKT, Th17, Treg, and CD8⁺ memory cells (12 - 16). An important component of these functions is the ability of
IL-15 to induce dendritic cell differentiation and inflammatory activation (11, 14). IL-15 exhibits anti-tumor activity independent of its actions on NK cells or CD8⁺ T cells (17). It also inhibits the deposition of lipid in adipocytes, and its circulating levels are decreased in obesity (18).

Product Specific Notices for ProDots Recombinant Human IL-15 GMP Protein

The GMP ProDot bag(s) should be used after proper inspection. Assess the bags after media is added to the bag either through the weldable port or needless valve. Inspect the bag to ensure complete dissolution of the GMP ProDot, and visually inspect seals and corners for a complete seal.

GMP ProDots are fragile. Please handle with care. If breakage of a ProDot is observed, there is no integrity lost, and can be used as indicated.

SDS-PAGE Purity, Host Cell DNA, and Host Cell Protein testing were completed on protein prior to lyophilization.

The End User is aware that R&D Systems, Inc. sells GMP products for preclinical or clinical ex vivo use and not for in vivo use. The End User Terms of Use of Product may be found at: RnDSystems.com/Legal .
