Goat anti-Mouse IgG3 Secondary Antibody

Mouse

Dot Blot, ELISA, Western Blot

Unconjugated

Polyclonal Goat

LYOPH mg/ml

Pools of purified homogenous IgG3 isolated from pooled mouse serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

This IgG fraction is not species-specific since inter-species cross-reactivity is a normal feature of antisera to immunoglobulins. However this product has been passed over appropriate immunoadsorbents to remove antibodies cross-reacting with Human immunoglobulins. This renders it specific for use in test systems containing material of Human origin (e.g. Human tissue/Mouse monoclonal antibody to a Human tissue constituent/anti Mouse Ig isotype-specific immunoconjugate. If the IgG fraction is to be used in the presence of material originating from another species, prior screening for cross-reactivity is essential an additional adsorption of the reagent may required to ensure intra-assay specificity.

The reactivity of the antiserum is directed to the subclass IgG3. It does not react with other subclasses of IgG, IgG/Fab fragments, IgM and IgA or any non-Ig protein in mouse serum, as tested by immunoelectrophoresis and double radial immunodiffusion.

The lyophilized IgG (7S) 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)
