    Recommended Assay Procedures

    ELISA Detection: The Biotinylated M182 antibody (Cat. No. 552503) is useful as a detection antibody for a sandwich ELISA measuring human IL-6Ra protein levels. Biotinylated M182 antibody can be paired with the purified M5 anti-human IL-6Ra (Cat. No. 551462) as the capture antibody, with recombinant soluble IL-6Ra (please inquire) as the standard. Biotin M182 antibody should be titrated between 0.5-2 µg/ml to determine its optimal concentration for ELISA capture. To obtain linear standard curves, doubling dilutions of recombinant human soluble IL-6Ra, ranging from 500 to 2 pg/ml are recommended for inclusion in each ELISA plate. For specific methodology, see BD Pharmingen's Immune Function Handbook, which is posted on our website at www. BDBiosciences.com.

    Note: This ELISA antibody pair shows no cross-reactivity with the following recombinant human cytokines:

    CD40, CD40L, CD14, IL-1Ra, IL-1R1, IL-1RII, IL-1α, IL-1ß, IL-2, IL-3, IL-4, sIL-4R, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12p40, IL-12p70, IL-13, IL-15, TNF-α, TNF-ß, sTNFRI, sTNFRII, IFNγ, TRAIL, GM-CSF, TGFß, Trx.

    Product Notices

    1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
    2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
    3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

    M182

    The M182 antibody reacts with the a subunit of the human IL-6 Receptor (IL-6Rα, aka, CD126). The human IL-6Rα is an 80 kDa type I transmembrane glycoprotein, also known as B cell stimulatory factor-2 (BSF-2) receptor and IL-6 receptor. The IL-6Rα subunit associates with the 130-160 kDa gp130 subunit (IL-6 receptor ß chain, CD130), that is shared with the receptors for Leukemia Inhibitory Factor (LIF), Ciliary Neurotropic Factor (CNTF), Oncostatin M (OSM), IL-11, Cardiotropin 1 (CT-1) and possibly Neurotrophin-1/B Cell-Stimulating Factor 3 (NNT-1/BSF-3). The IL-6Rα chain binds IL-6 with low affinity, however the association with CD130 stabilizes the IL-6/IL-6Rα complex resulting in the formation of a high affinity complex. The IL-6R ß chain mediates signal transduction. IL-6Rα's are expressed at high levels by activated and EBV-transformed B cells, plasma cells and myeloma cells and at lower levels by most leucocytes, epithelial cells, fibroblasts, hepatocytes and neural cells. IL-6Rα exists in soluble form in human serum. The serum levels of soluble IL-6Raappear to elevate in pathological situations such as multiple myeloma, Grave's disease, juvenile chronic arthritis and HIV.10-13 The immunogen used to generate the M182 hybridoma was a mixture of U266, XG-1 (human myeloma cell line expressing membrane IL-6R) and BWD41 cells (murine thymoma cell line transfected with cDNA encoding the extracellular part of IL-6Rα).

    Biotin
    Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
