| Product Name | Rabbit IgG Against Sheep IgM |
|---|---|
| Catalog Number | orb21557 |
| Species/Host | Rabbit |
| Conjugation | Unconjugated |
| Tested applications | DOT, IEP |
| Immunogen | Purified normal IgM isolated from pooled sheep serum. Freunds complete adjuvant is used in the first step of the immunization procedure. |
| Target | IgM. The reactivity of the antiserum is directed to the Fc subunit of the IgM molecule which expresses strict isotypic (class) specificity. It does not react with any non-Ig protein in sheep serum, as tested by immunoelectrophoresis and double radial immunodiffusion. |
| Form/Appearance | Vial with 10 mg lyophilized IgG (7S) fraction. |
| Concentration | IgG protein concentration 1 mg/ml. No foreign proteins added. |
| Preservatives | No preservative added, as it may interfere with the antibody activity. |
| Storage | The lyophilised IgG fraction is shipped at ambient temperature and may be stored at 4°C; prolonged storage at or below -20°C. 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. 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. |
| Note | For research use only. |
| Clonality | Polyclonal |
| Adsorption | Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibodies cross- reacting with other components of the immunoglobulin system or reacting with other serum proteins. Special attention is given to the removal of antibodies to common Ig/Fab. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum. |
| Application Notes | Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail, however a strong reaction with goat IgM has been observed. Experiment Notes: Hyperimmune antisera with strong precipitating activity are selected for fractionation by salt- precipitation and purification of the IgG fraction by DEAE-chromatography. |
