This antibody is specific to the kappa light chain of immunoglobulin and shows no cross-reaction with lambda light chain or any of the five heavy chains. In mammals, the two light chains in an antibody are always identical, with only one type of light chain, kappa or lambda. In general, the ratio of Kappa to Lambda is 3:1. However, with the occurrence of multiple myeloma or other B-cell malignancies this ratio is disturbed. Antibody to the kappa light chain is reportedly useful in the identification of leukemias, plasmacytomas, and certain non-Hodgkin"s lymphomas. Demonstration of clonality in lymphoid infiltrates indicates that the infiltrate is malignant.

The concentration stated for each application is a general starting point.Variations in protocols, secondaries and substrates may require the Kappa antibody to be titered up or down for optimal performance.

1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

Human Kappa light chain was used as the immunogen for this Kappa antibody.

Store the Kappa antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
