This antibody reacts with immunoglobulin Ig delta chains, cytoplasmic proteins strongly expressed by naive/mantle zone B-cells and a small subset of plasma cells, and weakly expressed by germinal center B cells. This antibody is useful in identifying leukemias, plasmacytomas, and B-cell lineage lymphomas, as well as a subset of B-cell non-Hodgkin lymphomas and normal mantle zone B-lymphocytes.
A formalin-fixed, paraffin-embedded (FFPE) tissue block is preferred specimen typeorOne (1) unbaked, unstained slide for H&E staining (required) and two to three (2-3) positively charged unstained slides (all cut at 4-5 microns) for each test/antibody orderedBlock and slide identifiers should be clearly written and match exactly with the specimen ID and specimen labeling as noted on the requisition.
Use cold pack for transport. Make sure cold pack is not in direct contact with specimen.
