Product specifications

Intended use

EyraPlex: Proinflammatory (8-plex) is intended for the quantification of human IFN-γ, IL-1β, IL-6, IL-8 (CXCL8), IL-10, IL-12 (p70), IL-13, and TNF-α in serum, plasma, and cell culture supernatants. The assay is designed for analysis using Mabtech EYRA™, but can also be used in flow cytometry. For research use only. Not for use in diagnostic procedures.

Introduction

EYRAplex is a magnetic bead-based multiplex assay for the simultaneous detection and quantification of multiple analytes in a single sample. The magnetic beads have been dyed with different concentrations of two fluorophores, resulting in distinct bead populations with unique bead IDs. Each bead population has been conjugated with a specific monoclonal antibody, allowing specific binding to its corresponding analyte. Multiplex analysis is enabled by combining several bead populations that are supplied as a capture bead mix.

In EYRAplex, the capture bead mix is added to wells in a 96-well plate. Samples and standards are then added. During incubation, the capture antibodies bind to analytes present in the sample. Detection occurs in two steps. First, a biotin-labeled monoclonal antibody mix (detection mAb mix) is added. These detection antibodies bind to the captured analytes. Streptavidin-PE is then added, binding to the biotin and generating a fluorescent signal proportional to the analyte concentration.

The fluorescent signal from each bead ID determines the analyte, while the streptavidin-PE signal reflects its quantity. Analytes are quantified by comparing the signals to standard curves.

Serum/Plasma samples

EYRAplex is designed to minimize interference from heterophilic antibodies and rheumatoid factor (RF), which can lead to false-positive results in immunoassays. The assay has been validated using serum and plasma samples from healthy donors, as well as samples containing elevated RF levels.

IFN-γ

Analyte description

Interferon-γ (IFN-γ) is the only type II interferon. This proinflammatory cytokine is secreted by activated T cells and NK cells. It activates macrophages and endothelial cells and regulates immune responses by affecting APCs, T cells, and B cells. Production of IFN-γ by helper T cells and cytotoxic T cells is a hallmark of the Th1-type phenotype. Thus, high-level production of IFN-γ is typically associated with effective host defense against intracellular pathogens.

Alternative namesInterferon-γ, Interferon-gamma, IFN-γ, IFN-gamma, IFN-g, IFNg
Cell typeT cell, Tc, Th1, NK cell

IL-1β

Analyte description

Interleukin 1ß (IL-1ß) is a proinflammatory cytokine and inducer of acute phase responses. IL-1ß is produced primarily by monocytes, macrophages, and dendritic cells after induction by microbes.
 

Alternative namesInterleukin-1ß, IL-1ß, IL-1F2, Interleukin-1beta, IL-1 beta, IL1b, Interleukin-1 beta
Cell typeMonocyte/MΦ, mDC

IL-6

Analyte description

Interleukin 6 (IL-6) is a pleiotropic cytokine produced by many different cell types and plays a role in a wide range of functions, such as immune responses, acute-phase reactions, and hematopoiesis. Among other things, it augments antibody production from activated B cells in vitro.

Alternative namesInterleukin 6, IL-6, IL6, IFB-B502, BSF-2, BCDF
Cell typeB cell, Monocyte/MΦ, mDC

IL-8 (CXCL8)

Analyte description

Interleukin 8 (IL-8) is a proinflammatory cytokine produced by different types of cells, including monocytes, macrophages, and endothelial cells. Inflammatory stimuli, such as LPS, strongly induce IL-8 production by monocytes.

Alternative namesInterleukin-8, IL-8, IL8, CXCL8
Cell typeT cell, Treg, Tfh, Monocyte/MΦ, mDC

IL-10

Analyte description

Interleukin 10 (IL-10) is a pleiotropic cytokine produced by activated T cells and monocytes. It can modulate the functions of immune responses in both a stimulatory and an inhibitory way. IL-10 is thereby involved in the regulation of immune reactions and inflammatory responses.

Alternative namesInterleukin-10, IL-10, IL10
Cell typeT cell, Treg, Monocyte/MΦ, mDC

IL-12 (p70)

Analyte description

Interleukin 12 (IL-12) is, when biologically active, a heterodimer (p70) consisting of two covalently linked subunits, p35 and p40. The p40 subunit is shared with IL-23. IL-12 is produced by antigen-presenting cells, specifically dendritic cells, and macrophages. IL-12 is a proinflammatory cytokine that promotes Th1-type responses by inducing IFN-γ production and enhancing the proliferation and cytotoxicity of NK and T cells.

Alternative namesInterleukin 12, IL-12, IL12
Cell typeMonocyte/MΦ, mDC

IL-13

Analyte description

Interleukin 13 (IL-13) is produced by Th2-type cells, mast cells, and NK cells in response to activation. It regulates the secretion of IgE by B cells and the Th2-type cell development and suppresses inflammatory responses by regulation of macrophage function.

Alternative namesInterleukin 13, IL-13, IL13
Cell typeT cell, Th2, Treg

TNF-α

Analyte description

Tumor necrosis factor (TNF), also known as TNF-α, is produced by many different cell types, e.g., monocytes, macrophages, T cells, and B cells. Among the many effects of TNF-α are protection against bacterial infection, cell growth modulation, immune system regulation, and involvement in septic shock.

Alternative namesTumor necrosis factor-α, TNF-α, TNF-alpha, TNF-a, TNFa, Tumor necrosis factor-alpha, TNF
