IgG2ab (subclass specific) polyclonal, anti-rat

Quantity: 1 ml

Background:
The reactivity of the antiserum is directed to the subclasses IgG2a and IgG2b as tested by immunoelectrophoresis and double radial immunodiffusion against rat sera and a panel of purified homogenous immunoglobulins. It does not react with other subclasses of IgG, IgG/Fab fragments, gM and IgA or any non-Ig protein in rat serum. As unlabelled primary or secondary reagent for indirect detection of IgG2a at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates; to prepare conjugates of the user's own choice; to prepare an insoluble immunoaffinity adsorbent or a solid phase antibody reagent by coupling to an artificial carrier and as catching antibody in non-isotopic methodology and solid phase immunochemistry.When applied in any cytochemical or histochemical staining procedure or solid phase coupling technique, the optimum concentration of the IgG preparation should be established by titration before being used.Typical working dilutions in histochemistry are usually between 1:100 and 1:250; in ELISA and comparable non-precipitating antibody-binding assays between 1:500 and 1:5,000.

Isotype: Goat Polyclonal

Source: Pools of purified homogenous IgG2a and IgG2b isolated from rat serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Purified hyperimmune goat IgG, in phosphate buffered saline (PBS, pH 7.2)

Specificity:
IgG fraction of polyclonal Goat anti-Serum to Rat IgG2ab, subclass specific

Reactivity: rat

Cross Reactivity:
This IgG fraction is not species-specific since inter-species cross-reactivity is a normal feature of antisera to immunoglobulins. Cross-reactivity of this product has not been tested in detail.

Applications: Indirect immunofluorescence, ELISA, Dot blot, Immunoblotting

Storage: Store at 4C, or in small aliquots at -20C.
