Ig kappa light chain (free and bound) polyclonal biotin, anti-human

Quantity: 1 ml

Background:
The reactivity of the antiserum is directed to the surface and hidden determinants of Ig kappa chain. A reaction is obtained with intact polyclonal or monoclonal immunoglobulins of the kappa type, as well as free kappa light chains. To identify light chain type in immunocytochemical and immunohistochemical staining of immunoglobulins and to demonstrate circulating monoclonal immunoglobulins and Bence Jones proteins of the kappa type in serum or other body fluids. As a second step an avidin or streptavidin conjugate of the user's choice has to be used. 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 fro histochemical and cytochemical use are usually between 1:100 and 1:500; in ELISA and comparable non-precipitating antibody-binding assays between 1:1,000 and 1:5,000.

Isotype: Rabbit Polyclonal

Source: A pool of purified Bence Jones kappa proteins isolated from human urine. Freund's complete adjuvant is used in the first step of the immunization procedure.

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

Reactivity: human

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 not been tested in detail.

Applications: ELISA, Immunocytochemistry, Immunohistochemistry (paraffin), Dot blot, Immunoblotting

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