Cytokine 4-Plex C
(IL-2, IL-6, IL-8, IFN-γ)
The Simoa® Cytokine 4-Plex C (C4PC) Advantage PLUS Assay (Product # 105066) measures IL-2, IL-6, IL-8, and IFN-γ at levels as low as fg/mL, providing reliable quantification of these key proinflammatory cytokines. The levels of these 4 cytokines measured in blood offer valuable insights into inflammation and immune responses to various conditions, including infections, injuries, cancers, and medical interventions such as immunotherapy. The fully automated HD-X Analyzer provides scalability of up to 6 plates in an 8-hour day, accomplishing in a single day what manual preparation methods would take a week to complete.

The target cytokines of Simoa® C4PC Advantage PLUS
IL-2: IL-2 is a potent pleiotropic cytokine primarily produced by CD4+ T cells upon antigen activation. IL-2 plays an important immune-modulating roles in resting and activated states of the immune system. It promotes the proliferation of cytotoxic effector cells that help the body fight against infections and eliminate cancer cells. It is also required for the expansion of Treg cells that are key for maintaining immune tolerance. IL-2 has therapeutic implications in immunotherapy, autoimmune disease and transplantation.
IL-6: IL-6 is a broad-acting cytokine that elicit both pro-inflammatory and anti-inflammatory outcomes
It is rapidly induced upon tissue damage or inflammation due to infections or injuries, stimulating acute phase immune reactions. IL-6 also plays a key role in adaptive immunity by promoting the differentiation of activated B cells into antibody-producing cells and naïve T cells into effector T cells. Dysregulated IL-6 has been implicated in autoimmune disease, chronic inflammatory disorders and cancers.
IL-8: IL-8 is a major pro-inflammatory mediator produced under inflammatory conditions by immune and other cell types. The most prominent role of IL-8 is attracting neutrophils to the sites of inflammation, while also contributes to promoting the proliferation and differentiation of monocytes, endothelial cells and angiogenesis.
IFN-γ: IFN-γ is a cytokine produced by activated CD4+ T cells, natural killer cells and macrophages. It is a critical mediator of immunity and inflammation with antiviral, antitumor and immunomodulatory functions. Its role in immune surveillance makes IFN-γ a potential therapeutic agent for cancer and certain infections. IFN-γ can contribute to autoimmunity and chronic inflammation under pathological conditions, presenting possibilities in treating these conditions by inhibiting IFN-γ.
Applications and Intended Use
The Simoa® C4PC Advantage PLUS is a digital immunoassay intended for the quantitative determination of IL-2, IL-6, IL-8, and IFN-γ concentrations in human serum and EDTA plasma samples.
