Rabbit anti Human Ig kappa light chain (free and bound) Antibody

IgG fraction of polyclonal rabbit antiserum to free and bound human Ig kappa light chain. This IgG preparation is intended for use in precipitating (gel diffusion) and non- precipitating antibody-binding immunoassays (indirect immunofluorescence, enzyme immunoassays for the detection of polyclonal immunoglobulins, purified monoclonal immunoglobulins of the kappa type as well as free light chains or Bence Jones proteins of the kappa type in serum or other body fluids; to prepare an insoluble immunoaffinity adsorbent or a solid phase catching antibody reagent by coupling to an artificial carrier; for labeling with a marker of the user's own choice. 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 1:500 and 1:5,000.
