| Product Name | Swine IgG Against Human IgG IgA IgM (TRITC) |
|---|---|
| Catalog Number | orb21662 |
| Species/Host | Porcine |
| Conjugation | TRITC |
| Tested applications | DOT, IEP |
| Immunogen | Purified immunoglobulin fractions containing IgG, IgA and IgM isolated from pooled human serum. Freunds complete adjuvant is used in the first step of the immunization procedure. |
| Target | Swine IgG Against Human IgG IgA IgM (TRITC). The reactivity of the antiserum is directed to the major isotypes of the human immunoglobulin system (classes and both light chain types) including antibodies to common determinants, to class and to the surface determinants of the common Fab portion, as tested by immunoelectrophoresis and double radial immunodiffusion against pooled serum and purified immunoglobulins. |
| Form/Appearance | Vial with 1 ml lyophilized immunoconjugate. |
| Concentration | IgG protein concentration 1 mg/ml. Fluorochrome/IgG protein molar ratio (F/P) is approximately 2.7. No foreign proteins added. |
| Preservatives | No preservative added, as it may interfere with the antibody activity. |
| Storage | The lyophilised conjugate 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 in the dark 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 immunoconjugate. |
| Note | For research use only. |
| Clonality | Polyclonal |
| Adsorption | Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibody activity with other serum protein. 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 immunoglobulins of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail. Conjugation Notes: A proprietary technique for the binding to TRITC is used, followed by several purification steps to remove free reactants and protein aggregates. After each step activity and specificity are tested in a variety of techniques. The conjugate is lyophilized to assure stability and long shelf life. Tetramethylrhodamine isothiocyanate isomer R. It has an orange-red fluorescence. Excitation: 554 nm, emission: 573 nm. To avoid nonspecific background staining, specially synthesized and exceptionally pure crystalline isomer R has been used instead of the usual racemic mixture. Although its fluorescence efficiency is less than of FITC, TRITC conjugates have the advantage of significantly less photo bleaching. This facilitates their use in quantitative cell-counting procedures. Experiment Notes: Hyperimmune antisera with strong precipitating activity are selected for fractionation by salt-precipitation and purification of the IgG fraction by DEAE-chromatography. |
