Overview
Host Type: Sheep
Antibody Clonality: Polyclonal
Regulatory Status: RUO
Target Species: Human
Applications:
- Dot Blot
- Enzyme-Linked Immunosorbent Assay (ELISA)
- Immunoblotting
- Immunohistochemistry (IHC)
Shipping:
Ship at ambient temperature.
Storage:
The lyophilized IgG fraction is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C. Prior to use an aliquot is thawed slowly at ambient temperature spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C not refrozen and preferably used the same day. If a slight precipitation occurs upon storage this should be removed by centrifugation. It will not affect the performance of the product
Further Information
Applications Description:
Indirect immunofluorescence,ELISA,Dot blot,Immunoblotting.
Background:
Tested in immunoelectrophoresis and double radial immunodiffusion against a panel of appropriate secretions and purified immunoglobulin isotypes. The antiserum reacts with both bound secretory component (secretory IgA) and with free secretory component. In immunoelectrophoresis against normal human milk, using a high electroendosmosis agar plate, free secretory component ism precipitated in the alpha-2 region. This antiserum does not react with other molecular forms of IgA, or with any other secretory or plasma protein and double radial immunodiffusion. As unlabelled primary or secondary reagent for indirect detection techniques, to prepare conjugates with markers of the user?s own choice, to prepare an insoluble immunoaffinity adsorbent or a solid phase antibody reagent by coupling to an artificial carrier and as catching or detection antibody in non-isotopic methodology and solid phase immunochemistry. When applied in any cytochemical or histochemical procedure or solids phase coupling technique, the optimum concentration of the IgG preparation should always be established by titration.

Product:
Purified hyperimmune sheep IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). No preservative added, as it may interfere with the antibody activity. No foreign protein added. It is reconstituted by adding 1 ml sterile distilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20°C.
Source:
Secretory component is present in human 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 65,000). The dimer IgA is transported into secretions by its binding to the SC on the epithelial cells. Under normal conditions, sIgA contains both subclasses IgA1 and IgA2, since both are capable of binding SC. Secretory component also has an affinity for polymeric IgM. Purified free human secretory component isolated from pooled milk is used for immunization. Freund?s complete adjuvant is used in the first step of the immunization procedure.
Specificity:
Purified IgG fraction of polyclonal sheep antiserum to human secretory component, free and bound.
