Invitrogen™ IFN gamma Chicken Matched Antibody Pair

Description

• The Chicken Interferon gamma Antibody Pair Kit comes with pre-matched antibody pairs, standards, and streptavidin-HRP to develop your own enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of chicken IFNγ
• Buffer reagents needed to complete the ELISA reaction are sold separate as a Buffer Kit for Antibody Pairs (Catalog No
• CNB0011)
• The Assay Buffer included in this Buffer Kit can be used as a blocking reagent for ELISA plates as well as a diluent for ELISA standards and samples, detection antibody, and HRP conjugate
• Principle of the method ELISAs are designed to measure the amount of the target bound between a matched antibody pair
• A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process
• Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody
• A sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal
• The intensity of this signal is directly proportional to the concentration of target present in the original specimen
• IFN gamma (Interferon gamma, Type II interferon) is a macrophage activation factor, and immune interferon that is produced primarily by T-lymphocytes and natural killer cells in response to antigens, mitogens, Staphylococcus enterotoxin B, phytohemaglutanin and other cytokines
• IFN gamma is a dimeric protein consisting of two 146 amino acid subunits
• IFN gamma is a glycoprotein that exists, functionally, as a homodimer of approximately 45 kDa
• On SDS-PAGE, IFN gamma appears as a combination of 25, 20 and minor 15.5 kDa bands as a result of differential glycosylation
• The biological activity of the IFN gamma homodimer is highly species specific
• Human IFN gamma does not show cross-reactivity with mouse
• IFN gamma function includes the following: antiviral activity, tumor antiproliferative activity, induction of class I and II MHC, macrophage activation, and enhanced immunoglobulin secretion by B lymphocytes
• IFN gamma is involved in cytokine regulation and also acts synergistically with other cytokines
• Activation of IFN gamma takes place through binding of IFN gamma receptor I and II, and activating the JAK-STAT pathway
• IFN gamma does not show any homology with IFN alpha or IFN beta but human IFN gamma shows about 40% sequence homology with mouse IFN gamma
• IFN gamma is upregulated by IL2, FGF basic, EGF and downregulated by vitamin D3 or DMN
• IFN gamma gene mutations are associated with aplastic anemia
