Background
The antiserum is reacting with the Fab subunit of intact IgG, IgA and IgM and other Ig classes of both light chain types, with their Fab or F(ab’)2 subunits and with free light chains of kappa and lambda type as tested in immunoelectrophoresis and double radial immunodiffusion. In precipitating techniques as immunoelectrophoresis and double radial immunodiffusion to identify the presence of Fab, free or bound.

Source
Purified Fab of normal rat IgG. Freund’s complete adjuvant is used in the first step of the immunization procedure.

Product
Delipidated, heat inactivated lyophilized stable whole serum. No preservative added. Total protein and IgG concentration in the antiserum are comparable to those of pooled sheep serum. No foreign proteins added. It is reconstituted by adding 1 ml sterile distilled water.

Formulation: Delipidated, heat inactivated lyophilized stable whole serum. No preservative added. Total protein and IgG concentration in the antiserum are comparable to those of pooled sheep serum. No foreign proteins added.

Specificity
Precipitating polyclonal Sheep antiSerum to Rat Fab of IgG.

Species Reactivity: Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiSerum has not been tested in detail, however in double radial immunodiffusion a reaction with Mouse and Human has been observed.

Applications
Precipitation assays. In immunoelectrophoresis use 2 μl or equivalent against 120 μl antiserum. In double radial immunodiffusion (Ouchterlony) use a rosette arrangement with 10 μl antiserum in a 3 mm diameter centre well and 2 μl serum samples (neat and diluted) in 2 mm diameter peripheral wells.

Storage
The lyophilized antiserum is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C. Working dilutions are prepared 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 product.
