Scientific Data Examples for ProDots Recombinant Human IL-2 GMP Protein

	ProDots Recombinant Human IL-2 GMP Protein GMP-grade ProDots^®Recombinant Human IL-2 (Catalog # PRD202-GMP) stimulates cell proliferation of the CTLL‑2 mouse cytotoxic T cell line. The ED₅₀ for this effect is 0.05-0.25 ng/mL. Three independent lots were tested for activity and plotted on the same graph to show lot-to-lot consistency of GMP IL-2.
	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-2 ProDot (PRD202-GMP) or GMP IL-2 202-GMP shows comparable A. T cell fold expansion and B. phenotype.

Background: IL-2

Interleukin-2 (IL-2) is a O-glycosylated, four alpha -helix bundle cytokine that has potent stimulatory activity for antigen-activated T cells. It is expressed by CD4⁺ and CD8⁺ T cells, gamma δ T cells, B cells, dendritic cells, and eosinophils (1-3). Mature human IL-2 shares 56% and 66% aa sequence identity with mouse and rat IL-2, respectively. Human and mouse IL-2 exhibit cross-species activity (4). The receptor for IL-2 consists of three subunits that are present on the cell surface in varying preformed complexes (5-7). The 55 kDa IL-2 R alpha is specific for IL-2 and binds with low affinity. The 75 kDa IL-2 R beta, which is also a component of the IL-15 receptor, binds IL-2 with intermediate affinity. The 64 kDa common gamma chain gamma c/IL-2 R gamma, which is shared with the receptors for IL-4, -7, -9, -15, and -21, does not independently interact with IL-2. Upon ligand binding, signal transduction is performed by both IL-2 R beta and gamma c. IL-2 is best known for its autocrine and paracrine activity on T cells. It drives resting T cells to proliferate and induces IL-2 and IL-2 R alpha synthesis (1, 2). It contributes to T cell homeostasis by promoting the Fas-induced death of naïve CD4⁺ T cells but not activated CD4⁺ memory lymphocytes (8). IL-2 plays a central role in the expansion and maintenance of regulatory T cells, although it inhibits the development of Th17 polarized cells (9-11). Thus, IL-2 may be a key cytokine in the natural suppression of autoimmunity (12, 13).

Product Specific Notices for ProDots Recombinant Human IL-2 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.
