| Description | Human Complement fragment 5b (C5b) ELISA Kit has high sensitivity and excellent specificity for detection of Human C5b. No significant cross-reactivity or interference between Human C5b and analogues was observed. The complement system is a part of the immune system that enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promotes inflammation, and attacks the pathogen's plasma membrane. It is part of the innate immune system, which is not adaptable and does not change over the course of an individual's lifetime. It can be recruited and brought into action by the adaptive immune system. The complement system consists of a number of small proteins found in the blood, in general synthesized by the liver, and normally circulating as inactive precursors (pro-proteins). When stimulated by one of several triggers, proteases in the system cleave specific proteins to release cytokines and initiate an amplifying cascade of further cleavages. The end result of this complement activation or complement fixation cascade is stimulation of phagocytes to clear foreign and damaged material, proxy inflammation to attract additional phagocytes, and activation of the cell-killing membrane attack complex. Over 30 proteins and protein fragments make up the complement system, including serum proteins, serosal proteins, and cell membrane receptors. They account for about 10% of the globulin fraction of blood serum and can serve as opsonins. Three biochemical pathways activate the complement system: the classical complement pathway, the alternative complement pathway, and the lectin pathway. This Human Complement fragment 5b (C5b) ELISA Kit employs a two-site sandwich ELISA to quantitate C5b in samples. An antibody specific for C5b has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyC5b present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for C5b is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of C5b bound in the initial step. The color development is stopped and the intensity of the color is measured. |
