A monoclonal antibody (IHC600) against mutant BRAF (V600E) permits fast assessment of the mutant protein expression throughout a tumor sample in hairy cell leukemia, some melanomas, and some thyroid carcinomas. BRAF mutation is a strong molecular marker of poor prognosis in colorectal carcinoma (CRC), and can be used as evidence of a sporadic mechanism of mismatch repair deficiency.
- 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.
