T Cell Receptor beta (TCRβ) is used as a phenotypic marker for TCRβ expressing T-cells. TCRβ is expressed by thymocytes and a majority of peripheral (α/β TCR-bearing) T-cells. This antibody does not cross-react with γ/Δ TCR-bearing T-cells.
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.
