| Product Name | Donkey Serum Against Goat IgG |
|---|---|
| Catalog Number | orb22139 |
| 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 1 ml lyophilized antiserum. |
| Concentration | Total protein and IgG concentration in the antiserum are comparable to those of pooled donkey serum. No foreign proteins added. |
| Preservatives | No preservative added, as it may interfere with the antibody activity. No foreign protein added. |
| Storage | The lyophilised antiserum 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. Working dilutions are prepared 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 |
| 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. IE: In immunoelectrophoresis use 2 μl or equivalent against 120 μl antiserum. In double radial immunodiffusion (Ouchterlony) use a rosette arrangement with 10 ulantiserum in a 3 mm diameter centre well and 2 μl serum samples (neat and diluted) in 2 mm diameter peripheral wells. |
