  • Background
    Growth Differentiation Factor 15 (GDF-15), also called Macrophage Inhibitory Cytokine 1 (MIC-1). Expression of MIC-1 mRNA in monocytoid cells is up-regulated by a variety of stimuli associated with activation, including interleukin 1β, tumor necrosis factor α (TNF-α), interleukin 2, and macrophage colony-stimulating factor but not interferon γ, or lipopolysaccharide (LPS). It is highly expressed in cardiomyocytes, adipocytes, macrophages, endothelial cells, and vascular smooth muscle cells in normal and pathological condition. GDF-15 increases during tissue injury and inflammatory states and is associated with cardiometabolic risk. Increased GDF-15 levels are associated with cardiovascular diseases such as hypertrophy, heart failure, atherosclerosis, endothelial dysfunction, obesity, insulin resistance, diabetes, and chronic kidney diseases in diabetes. Increased GDF-15 level is linked with the progression and prognosis of the disease condition.
  • Application

    This kit is developed for screening for inhibitors of human GDF-15 binding to human GFR alpha-like.

    It is for research use only.

  • Reconstitution
    Please see Certificate of Analysis for details of reconstitution instruction and specific concentration.
  • Storage
    Unopened kit should be stored at 2°C -8°C upon receiving.

    Find the expiration date on the outside packaging and do not use reagents past their expiration date.

    The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

  • Assay Principles
    This inhibitor screening ELISA kit is designed to facilitate the identification and characterization of new OX40 pathway inhibitors. The assay takes advantage of our in house-developed binding of biotinylated human OX40 to immobilized human OX40 Ligand in a functional ELISA assay, and employs a simple colorimetric ELISA platform. Briefly, we provide you with a human Biotinylated OX40 protein, a human OX40 Ligand protein, an anti-OX40 neutralizing antibody (as method verified Std.), and Streptavidin-HRP reagent.

    Your experiment will include 4 simple steps:

    a) Coat the plate with human OX40 Ligand.

    b) Add your molecule of interest to the tests.

    c) Add Biotinylated Human OX40 to bind the coated OX40 Ligand.

    d) Add Streptavidin-HRP followed by TMB or other colorimetric HRP substrate.

    Finally, the half maximal inhibitory concentration (IC50) of your compound to OX40 : OX40 Ligand binding will be determined by comparing OD readings among different experimental groups.

Typical Data Please refer to Ds document for the assay protocol.
 GDF-15 TYPICAL DATA

INHIBITION OF GDF15 [Biotinylated]: GFRAL BINDING BY ANTI-GDF15 NEUTRALIZING ANTIBODY
Serial dilutions of Anti-GDF15 Neutralizing Antibody (Catalog # EP164-C04) (1:1 serial dilution, from 2 μg/mL to 0.000976563μg/mL) was added into GDF15 [Biotinylated]: GFRAL binding reactions. The assay was performed according to the protocol described below. Background was subtracted from data points prior to log transformation and curve fitting (QC tested).
