Characterization

Description:

The Unfolded Protein Response (UPR) is a conserved and essential stress response that cells activate to combat endoplasmic reticulum (ER) stress, commonly caused by the accumulation of misfolded proteins or failing protein quality control.   UPR signaling has been identified as one of the avenues leading to the inflammatory response. The integration of ER stress, oxidative stress and the inflammatory response is critical to the pathogenesis of a variety of diseases, such as  diabetes, Alzheimer’s, Parkinson’s, and obesity.  It has been demonstrated that some cytokines can activate ER Stress and that ER stress can increase the expression of certain cytokines as well.  Therefore, cytokine profiling provides a valuable tool for examining the relationship between cytokine expression and ER stress response.  Signosis’ ER stress ELISA Strip allows quantitative profiling and measures 8 ER stress-associated cytokines. The list of cytokines is as follows: TNFα, IL-1β,IFNγ, IL-6 ,IGF-1, MCP-1, Leptin and TGFβ .

Principle

Each well of the strip is coated with a specific capture antibody to detect its corresponding cytokine in the sample. Therefore, 8 different proteins can be measures simultaneously. The test sample reacts simultaneously with two antibodies, resulting in the cytokines being sandwiched between the solid phase and enzyme-linked antibodies. After incubation, the wells are washed to remove unbound-labeled antibodies. The HRP substrate, TMB, is then added and causes a blue color change. The reaction is then terminated with Stop Solution, resulting in a yellow color. The concentrations of oxidative stress cytokines are directly proportional to the color intensity of the test sample. Absorbance is measured spectrophotometrically at 450 nm. The expression levels of these cytokines can be quantitatively compared between samples.
