IgG (heavy and light chains) polyclonal TRITC, anti-canine

Quantity: 200 µl

Background:
The reactivity of the antiserum is directed to the Fc and Fab subunits of the IgG molecule. It includes a certain degree of reactivity with other immunoglobulins via the common Fab portion. It does not react with any non-Ig protein in dog serum, as tested by immunoelectrophoresis and double radial immunodiffusion. To identify and measure IgG, antigen or antibody, at the cellular and subcellular level by immunofluorescence staining of appropriately treated cell and tissue substrates. If two Nordic immunoconjugates with different labels but originating from the same host animal species are used for direct two-colour staining, they can safely be mixed and used in a single step, without the danger of interaction between the two reagents. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Working dilutions are usually between 1:20 and 1: 80.

Isotype: Rabbit Polyclonal

Source: Purified normal IgG isolated from pooled dog serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: TRITC-coupled purified hyperimmune rabbit IgG, in phosphate buffered saline (PBS, pH 7.2).

Reactivity: Canine

Cross 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 been tested in double radial immunodiffusion with the following results: Bovine - Cat + Chicken - Duck - ferret + Goat - Guinea Pig + Hamster + Horse + Human + Mouse + Monkey + pigeon - Rat + Sheep - Swine + Turkey - A negative cross-reaction in double radial immunodiffusion does not exclude some reaction in more sensitive techniques.

Applications: ELISA, Immunocytochemistry, Immunohistochemistry (frozen), (In)direct immunofluorescence

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