背景介绍
  • TNF-α, which stands for Tumor Necrosis Factor-alpha, is a potent signaling molecule crucial for immune system regulation. It is primarily produced by activated macrophages, but also by other immune cells like T lymphocytes and mast cells. Its main role is to orchestrate inflammation, a key defense mechanism against infection and injury. TNF-α promotes the activation of immune cells and induces fever by acting on the hypothalamus. Furthermore, it can trigger programmed cell death (apoptosis) in certain tumor cells, which is how it earned its name. While essential for host defense, excessive or chronic production of TNF-α is a major driver of inflammatory diseases, such as rheumatoid arthritis and Crohn's disease. This has made it a critical therapeutic target, with drugs blocking TNF-α being widely used. In essence, TNF-α is a master regulator of inflammation, with powerful but potentially harmful effects that must be tightly controlled.

    • Standard curve
      Example of Human TNF-α standard curve in Assay Diluent #12E7.

    • Linearity
      The concentrations of Human TNF-α were measured and interpolated from the target standard curves and corrected for sample dilution.
      Sample is undiluted samples are as follows: human PBMC cells stimulated with 5ug/ml LPS and 50uM PMA for 5days (12.5%). The interpolated dilution factor corrected values are plotted. The mean target concentration was determined to be 5201.87 pg/mL in stimulated human PBMC supernatant.

    • To assess the linearity of the assay, three samples were spiked with high concentrations of Human TNF-α in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
