Secretory Component

Secretory component is present in monkey secretions bound to secretory IgA (sIgA) and in free\nform. Secretory IgA (sIgA) functions as a dimer or polymer and accounts for almost all specific\nmucosal antibody activity. A molecule of sIgA is made up of two molecules of IgA, one J chain\nand one SC (MW 65000). The dimer IgA is transported into secretions by its binding to the SC on the epithelial cells. SC also has an affinity for polymeric IgM. \n\nApplications: \nSuitable for use in ELISA, Immunoelectrophoresis and Double Radial Immunodiffusion. Other applications not tested.\n\nRecommended Dilution:\nELISA: 1:200-1:1000\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Additional Info

Recognizes monkey secretory component. Reacts with both bound secretory component (secretory IgA) and with free secretory component. In immunoelectrophoresis against normal\nmonkey milk, using a high electroendosmosis agar plate, free secretory component is precipitated in the alpha-2 region. Does not react with other molecular forms of IgA, or with any other secretory or plasma proteins. May also react with free and bound secretory component in many old-world monkeys, including Macaca, Sylvanus, Cercopithecus, Cynomolgus, Baboon and \nchimpanzees. In double radial immunodiffusion a reaction has been observed with free human secretory component.
