Goat anti-Mouse IgE Fc Secondary Antibody

Mouse

Dot Blot, ELISA, Immunoblotting, Immunocytochemistry/ Immunofluorescence, Western Blot

Unconjugated

Polyclonal Goat

LYOPH mg/ml

Purified homogenous IgE isolated from mouse serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

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 because of the low level of IgE in most species.

The reactivity of the antiserum is directed to the Fc subunits of the IgE molecule which represents strict isotype (class) specificity. In immunoelectrophoresis and double radial immunodiffusion, using various antiserum concentrations against appropriate concentrations of IgE, a single precipitin line is obtained which shows a reaction of full identity with the precipitin line obtained with the used immunogen. It does not react with mouse IgG, including all subclasses, IgA, IgM and IgG/Fab or any non-Ig protein in mouse serum.

The lyophilized IgG fraction is shipped at ambient temperature and may be stored at 4C; prolonged storage at or below -20C. 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 4C, 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.

Ion exchange chromatography

Reconstitute by by adding 1 ml sterile distilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20C.

Lyophilized from PBS (pH 7.2)

No Preservative

The product is shipped with polar packs. Upon receipt, store it immediately at the temperature recommended below.

Store at 4C short term. Aliquot and store at -20C long term. Avoid freeze-thaw cycles.
