Methodology
Immunohistochemistry (IHC)
Test Description
B-cell lymphoma 2 (BCL2) was the first of the translocation-associated proteins to be identified in lymphoma. Most cases of follicular lymphoma have a [t(14;18)] translocation, resulting in BCL2 overexpression. Overexpression of BCL2 in activated diffuse B-cell lymphoma may predict disease progression. BCL2 is also expressed in a wide range of other neoplasms.
Specimen Requirements
- A formalin-fixed, paraffin-embedded (FFPE) tissue block is preferred specimen type
or - 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.
