Spotlight on NKX3.1
NKX3.1 is a prostate-specific homeobox gene protein whose expression is predominantly localized to prostate epithelium. It acts as a transcription factor involved in prostate development. Anti-NKX3.1 labels prostate epithelium, both malignant and benign, with a nuclear visualization.
Studies have shown that NKX3.1 immunostaining compares favorably to PSA immunostaining in sensitivity of metastatic prostate adenocarcinoma.1 NKX3.1 is recommended to be included in a diagnostic panel with PSA, PSAP, cytokeratin 34betaE12, and GATA3.2
Benefits of Rabbit Monoclonal NKX3.1:
- In vitro diagnostic
- Nuclear visualization
- A study conducted by Gurel et al. shows that NKX3.1 is more sensitive than prostate specific antigen (PSA) for metastatic prostate carcinoma.1
- NKX3.1 has a 99.7% specificity for prostate.1
- NKX3.1 IHC is cited in the best practices recommendations for prostate in the International Society of Urologic Pathology consensus conference.2
