Mouse CFD (Complement Factor D) Microsample ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mouse CFD. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse CFD. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Mouse CFD, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Mouse CFD in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 0.16-10 µg/mL. Sensitivity: 0.056 µg/mL. Assay Type: Sandwich. Standard: 10 µg/mL. Sample Type: sSerum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids.. Assay duration: 3.5h. Protein Function: Serine protease that initiates the alternative pathway of the complement system, a cascade of proteins that leads to phagocytosis and breakdown of pathogens and signaling that strengthens the adaptive immune system. In contrast to other complement pathways (classical, lectin and GZMK) that are directly activated by pathogens or antigen-antibody complexes, the alternative complement pathway is initiated by the spontaneous hydrolysis of complement C3. The alternative complement pathway acts as an amplification loop that enhances complement activation by mediating the formation of C3 and C5 convertases. Activated CFD cleaves factor B (CFB) when the latter is complexed with complement C3b, activating the C3 convertase of the alternative pathway [The Uniprot Consortium]
