ICFC - Quality tested

Application Notes:

ELISA Capture1-3,11 or ELISPOT Capture4,5: The purified MP5-20F3 antibody is useful as the capture antibody in a sandwich ELISA or ELISPOT assay, when used in conjunction with the biotinylated MP5-32C11 antibody as the detecting antibody and recombinant mouse IL-6 as the standard.

Additional reported applications (for relevant formats of this clone) include: In Vivo Capture7, and immunohistochemical staining (paraformaldehyde-fixed/saponin-treated6, and acetone-fixed frozen tissue sections13, 14).

Recommended Usage:

The MP5-20F3 antibody reacts with mouse interleukin-6 (IL-6). The MP5-20F3 antibody can neutralize the bioactivity of natural or recombinant IL-6. Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Thioglycollate-elicited C57BL/6 mouse peritoneal macrophages

Thioglycollate-elicited C57BL/6 mouse peritoneal macrophages were stimulated with LPS for 6 hours (in the presence of monensin), then surface stained with anti-mouse CD107b/Mac-3 APC. This was followed by fixation and permeabilization and then stained with anti-mouse IL-6 (MP5-20F3) PE (top) or rat IgG1, κ PE isotype control (bottom).


IL-6 is a potent lymphoid cell growth factor that stimulates the growth and survivability of certain B cells and T cells. IL-6 plays a role in host defense, acute phase reactions, immune responses, and hematopoiesis. IL-6 is expressed by T cells, B cells, monocytes, fibroblasts, hepatocytes, endothelial cells and keratinocytes.

Other Names: Interleukin-6, B cell stimulating factor-2 (BSF-2), Cytotoxic T cell differentiation factor (CDF), Hepatocyte stimulating factor (HSF), Hybridoma/plasmacytoma growth factor (HPGF)
Structure: Neuropoietic cytokine family; 22-29 kD (Mammalian)
Regulation: Upregulated by IL-1, TNF, PDGF, IFN-β, TNF-α, NGF, IL-17; downregulated by glucocorticoids IL-4, TGF-β
Cellular Sources: T cells, B cells, macrophages, bone marrow stromal cells, fibroblasts, keratinocytes, mesangium, astrocytes, endothelial cells
Cellular Targets: T cells, B cells, hepatocytes, cholinergic neurons
Receptors: Heterodimer IL-6Rα (CD126)/IL-6Rβ (CD130; gp130)
Bioactivity/Activities: Hematopoiesis; antigen-specific immune responses, inflammatory reactions; acute phase reaction
