NKX2.1 Antibody / TTF1

• Catalog Number: orb606478
• Category: Antibodies
• Description: NKX2.1/TTF-1 is a member of the NKx2 family of homeodomain transcription factors. It is expressed in epithelial cells of the thyroid gland and the lung. Nuclei from liver, stomach, pancreas, small intestine, colon, kidney, breast, skin, testes, pituitary, prostate, and adrenal glands are unreactive. Anti-NKX2.1 is useful in differentiating primary adenocarcinoma of the lung from metastatic carcinomas originating in the breast, mediastinal germ cell tumors, and malignant mesothelioma. It can also be used to differentiate small cell lung carcinoma from lymphoid infiltrates. Loss of NKX2.1 expression in non-small cell lung carcinoma has been associated with aggressive behavior of such neoplasms. NKX2.1 reactivity is also seen in thyroid malignancies.
• Clonality: Recombinant
• Species/Host: Rabbit
• Isotype: Rabbit IgG, kappa
• Conjugation: Unconjugated
• Reactivity: Human, Mouse, Rat
• Immunogen: Recombinant protein was used as the immunogen for the recombinant NKX2.1 antibody.
• UniProt ID: P43699
• Tested applications: IHC-P
• Dilution range: Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT
• Application notes: Optimal dilution of the recombinant NKX2.1 antibody should be determined by the researcher.1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
