Specifications

Clone Host Grade Applications
Polyclonal Goat Highly Purified
Secretory component is present in monkey secretions bound to secretory IgA (sIgA) and in free
form. Secretory IgA (sIgA) functions as a dimer or polymer and accounts for almost all specific
mucosal antibody activity. A molecule of sIgA is made up of two molecules of IgA, one J chain
and 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.
Catalog #S0630-01M
ApplicationsSuitable for use in FLISA, Immunoelectrophoresis and Double Radial Immunodiffusion. Other applications not tested.

ConcentrationNot determined
FormSupplied as a lyophilized powder from PBS, pH 7.2. No preservatives added. Labled with Fluorescein isothiocyanate (FITC). Reconstitute in 1ml sterile ddH2O. Dilute further in PBS, pH 7.2.
PurityPurified by DEAE chromatography.
ImmunogenPurified free monkey secretory component isolated from pooled milk.
SpecificityRecognizes monkey secretory component. Reacts with both bound secretory component (secretory IgA) and with the free SC present in monkey secretions. In immunoelectrophoresis against monkey milk, using a high electroendosmosis agar plate, free SC is precipitated in the alph-2 region. Does not react with other molecular forms of IgA, or with any other secretory or plasma protein. Precipitation reactions have been observed with free and bound secretory component in serum of other old-world monkeys, including Cercopithecus, Cynomolgus and Baboon.
