Mouse IFN-γ ELISA Kit(Plus)

Detection Principle:

This kit uses double antibody sandwich ELISA technology. Specific anti- mouse  Ifn-&gamma  Capture antibody was pre coated on a high affinity microplate. Add the standard, the sample to be tested and the biotin labeled detection antibody into the wells of the enzyme plate in turn, shake well and mix well, and then place it at room temperature for 2 hours of incubation process. The ifn-&gamma in the sample  Bound to solid-phase antibody and detection antibody. After washing sufficiently to remove free and unbound components, streptavidin HRP (sa-hrp) labeled with horseradish peroxidase was added. After washing again, TMB chromogenic substrate was added and incubated at room temperature in the dark to develop color. The depth of color response and ifn-&gamma in the sample; There is a positive correlation between the concentration of. Add stop solution to stop the reaction, and use a microplate reader to measure the absorbance value at 450 nm detection wavelength (correction wavelength 570-630 nm)

Background:

γ interferon (IFN-γ)Is a soluble dimeric cytokine and is the only member of type II interferons. It is mainly secreted by natural killer (NK) and natural killer T (NKT) cells and plays a role in innate immunity; It is secreted by CD4 Th1 and CD8 cytotoxic T cells during antigen-specific immunity. IFN-γ Or type II interferons play an important role in innate and adaptive immunity against virus, some bacteria and protozoan infections. IFN-γ It is an important activator of macrophages and an inducer of major histocompatibility complex type II (MHC II) expression. IFN-γ The abnormal expression of Bcl-2 is associated with many autoinflammatory and autoimmune diseases. In addition to directly inhibiting viral replication, IFN-γ Its importance to the immune system is more reflected in its immune stimulation and immune regulation functions.
