Lambda Light Chain (P) Description
Lambda reacts with free lambda chains as well as lambda chains in intact immunoglobulin molecules. This antibody is useful in the identification of myelomas, plasmacytomas, and certain non-Hodgkins lymphomas. The most common feature of these malignancies is the restricted expression of a single light chain class. Demonstration of clonality in lymphoid infiltrates indicates that the infiltrate is clonal and therefore malignant.
