S100A8/S100A9 heterodimer (human) ELISA Kit

S100A8 and S100A9 are Ca2+ binding proteins that belong to the S100 family, called calgranulin. Calgranulins are endogenous molecules released in response to environmental triggers and cellular damage. Also known as Damage-Associated Molecular Pattern Molecules (DAMPs), these proteins play an important role in a diverse range of physiological and pathological processes, such as host defense, wound healing, autoimmunity, oncogenesis and inflammation, among others. This assay is a sandwich based ELISA kit allowing accurate quantification of S100A8/S100A9 heterodimers in human samples. Enzyme ImmunoAssay (EIA) is a technique to detect and quantify antigens (proteins, hormones) or antibodies in samples. It relies on the ability of an antibody to bind a specific antigen. Either the antibody or the antigen is labelled with an enzyme whose substrate is a chromogen or a fluorogen converted in a measurable product (color or fluorescence). Enzyme-linked Immunosorbent Assay (ELISA) is a type of EIA using a solid phase (ex: microtiter plate) coated with an antigen immobilizing the molecule to detect. Over the time, scientists have extended the term ELISA to EIAs using an antibody coating the solid phase. That explains why our EIA kits using coated antibodies are also called ELISA kits.
