Secretory component is present in monkey secretions bound to secretory IgA (sIgA) and in freeform.
Secretory IgA (sIgA) functions as a dimer or polymer and accounts for almost all specificmucosal antibody activity.
A molecule of sIgA is made up of two molecules of IgA, one J chainand 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.

仕様
Size：5mg
Host：goat
Source Antibody：monkey
Grade：Highly Purified
Purity：Purified by DEAE chromatography.
Form：Supplied as a lyophilized powder from PBS, pH 7.2. No preservatives added. Reconstitute in 1ml sterile ddH2O. Dilute further in PBS, pH 7.2.
Specificity：Recognizes monkey secretory component. Reacts with both bound secretory component (secretory IgA) and with free secretory component. In immunoelectrophoresis against normalmonkey 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 chimpanzees. In double radial immunodiffusion a reaction has been observed with free human secretory component.
Isotype：IgG

Calc Crossreactivity：Mk
Immunogen：Free monkey secretory component isolated from pooled milk.
