| Product Name | Donkey IgG Against Goat IgG |
|---|---|
| Catalog Number | orb22020 |
| Species/Host | Donkey |
| Conjugation | Unconjugated |
| Tested applications | DOT, IEP |
| Immunogen | Purified normal IgG isolated from pooled goat serum. Freunds complete adjuvant is used in the first step of the immunization procedure. |
| Target | IgG. The reactivity of the antiserum is directed to the Fc and Fab subunits of both subclasses, IgG1 and IgG2. It includes a certain degree of reactivity with other immunoglobulins via the common Fab portion. In immunoelectrophoresis against goat serum a single characteristic precipitin line with a spur is usually obtained, representing primarily IgG2. If the IgG1 level in the sample approaches the concentration of IgG2, it may become visible as a second precipitin line. It does not react with any non-Ig protein in goat serum, as tested by immunoelectrophoresis and double radial immunodiffusion. |
| Form/Appearance | Vial with 10 mg lyophilized purified hyperimmune IgG. |
| Concentration | IgG protein concentration 1 mg/ml. No foreign proteins added. |
| Preservatives | No preservative added, as it may interfere with the antibody activity. No foreign protein added. |
| 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 t o 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 | No adsorption required. |
| 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 was observed with sheep, a moderate reaction with swine and less with rabbit, as tested in double radial immunodiffusion. Experiment Notes: Hyperimmune antisera with strong precipitating activity are selected for fractionation by salt- precipitation and purification of the IgG fraction by DEAE-chromatography. |
