CD2, the E-rosette receptor, is an extremely broad T-cell marker. This antibody immunostains the vast majority of T-cells and a subset of natural killer (NK) - cell malignancies. Half of thymic B-cells are also CD2 positive.
- A formalin-fixed, paraffin-embedded (FFPE) tissue block is preferred specimen type
- One (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 ordered
- Block 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.
