Papillary thyroid cancer with strong nuclear TRIM28 immunostaining of tumor cells.
Staining Pattern in Normal Tissues
Manual protocol
Freshly cut sections should be used (less than 10 days between cutting and staining). Heat-induced antigen retrieval for 5 minutes in an autoclave at 121°C in pH 7,8 Target Retrieval Solution buffer. Apply HMV335 at a dilution of 1:200 at 37°C for 60 minutes. Visualization of bound antibody by the EnVision Kit (Dako, Agilent) according to the manufacturer’s directions.

Biology behind
Tripartite motif-containing 28 (TRIM28), also termed KAP1 (KRAB-associated protein-1), or transcriptional mediator 1b (TIF1b) is a regulatory protein coded by the TRIM28 gene at chromosome 19q13.43. The protein plays a role in transcription regulation by interaction with the Krüppel-associated box repression domain found in many transcription factors and binding to specific chromatin regions. In addition to regulating gene transcription, KAP1 has a variety of regulatory intracellular functions, such as response to DNA damage, maintaining stem cell pluripotency, cellular differentiation and proliferation, viral suppression, and apoptosis. KAP1 is ubiquitously expressed, and its function depends on posttranscriptional modification.
