| Product Name | Goat IgG Fab Against Human IgM (FITC) |
|---|---|
| Catalog Number | orb21778 |
| Species/Host | Goat |
| Conjugation | FITC |
| Tested applications | DOT, IEP |
| Immunogen | Purified IgM prepared from pooled human serum. Freunds complete adjuvant is used in the first step of the immunization procedure. |
| Target | Goat IgG Fab Against Human IgM (FITC). The antiserum is reacting with to the Fc subunit of IgM. It does not react with other immuno- globulins or any non-Ig protein in human serum, as tested by immunoelectrophoresis and double radial immunodiffusion. |
| Form/Appearance | Vial with 1 ml lyophilized immunoconjugate. |
| Concentration | IgG protein concentration 1 mg/ml. Fluorochrome/IgG protein molar ratio (F/P) is approximately 1.6. No foreign proteins added. |
| Preservatives | No preservative added. |
| 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 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 dif- ferent species frequently share antigenic determinants. Cross-reactivity of this conjugate has not been tested in detail. Conjugation Notes: A proprietary technique for the binding to FITC 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. Fluorescein isothiocyanate isomer 1. Excitation: 492 nm, emission: 515 nm. Experiment Notes: Hyperimmune antisera with strong precipitating activity are selected for fractionation by salt- precipitation and purification of the IgG fraction by DEAE-chromatography. |
