| 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. |

| Clone Type | Polyclonal |
| Isotype | IgG |
| Host | Goat |
| Source | Monkey |
| Concentration | Not determined |
| 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. |
| Purity | Purified by DEAE chromatography. |
| Immunogen | Free monkey secretory component isolated from pooled milk. |
| Specificity | Recognizes monkey secretory component. Reacts with both bound secretory component (secretory IgA) and with free secretory component. In immunoelectrophoresis against normal |
| monkey 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. |
