Immunoglobulin G (IgG), is one of the most abundant proteins in human serum with normal levels between 8-17 mg/mL in adult blood. IgG is important for our defence against microorganisms and the molecules are produced by B lymphocytes as a part of our adaptive immune response. The IgG molecule has two separate functions; to bind to the pathogen that elicited the response and to recruit other cells and molecules to destroy the antigen. The variability of the IgG pool is generated by somatic recombination and the number of specificities in an individual at a given time point is estimated to be 1011 variants.

The reagent is an anti-mouse antibody F(ab′)2 fragment from goat. The F(ab′)2 fragments are obtained by pepsin cleavage. The fragments are conjugated to fluorescein isothiocyanate and stabilized in buffer. The molar ratio of fluorescein: protein is: 3 - 7.

PURIFICATION: The goat-lgG was purified by affinity chromatography and absorbed to remove cross-reactivity to human immunoglobulins.

Specific for mouse IgG, heavy and light chain. The cross-reactivities of the anti-mouse IgG antibody were tested in an ELISA. Minimum cross-reactivity to human IgG.

Immunohistochemistry: 1:200-1:500 (Coligan et al. 1997; Harlow & Lane 1988; Bullock & Petrusz 1982; Javois 1994)

Flow cytometery: 1 μg per 1 x 10E6 cells (Coligan et al. 1997; Harlow & Lane 1988; Javois 1994) FITC absorption peak is 488-492nm, its emission peak is 520nm.

Optimal working dilutions must be determined by the end user.
