A. Solutions and Reagents

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.

  1. Xylene.
  2. Ethanol, anhydrous denatured, histological grade (100% and 95%).
  3. Deionized water (dH2O).
  4. Hematoxylin (optional).
  5. Wash Buffer:
    1. 1X Tris Buffered Saline with Tween® 20 (TBST): To prepare 1L 1X TBST add 100 ml 10X Tris Buffered Saline with Tween® 20 (#9997) to 900 ml dH20, mix.
  6. SignalStain® Antibody Diluent (#8112).
  7. 1X Citrate Unmasking Solution: To prepare 250 mL of 1X citrate unmasking solution, dilute 25 ml of SignalStain® Citrate Unmasking Solution (10X) (#14746) with 225 mL of dH2O.
  8. 3% Hydrogen Peroxide: To prepare 100 ml, add 10 ml 30% H2O2 to 90 ml dH2O.
  9. Blocking Solution: TBST/5% Normal Goat Serum or 1X Animal-Free Blocking Solution.
    1. TBST/5% Normal Goat Serum: to 5 ml 1X TBST, add 250 µl Normal Goat Serum (#5425).
    2. 1X Animal-Free Blocking Solution: to 4 mL of dH2O add 1 ml of Animal-Free Blocking Solution (5X) (#15019).
  10. Detection System: SignalStain® Boost IHC Detection Reagents (HRP, Mouse #8125).
  11. Substrate: SignalStain® DAB Substrate Kit (#8059).
  12. Hematoxylin: Hematoxylin (#14166).
  13. Mounting Medium: SignalStain® Mounting Medium (#14177).

B. Deparaffinization/Rehydration

NOTE: Do not allow slides to dry at any time during this procedure.

  1. Deparaffinize/hydrate sections:
    1. Incubate sections in three washes of xylene for 5 min each.
    2. Incubate sections in two washes of 100% ethanol for 10 min each.
    3. Incubate sections in two washes of 95% ethanol for 10 min each.
  2. Wash sections two times in dH2O for 5 min each.

C. Antigen Unmasking

For Citrate: Heat slides in a microwave submersed in 1X citrate unmasking solution until boiling is initiated; follow with 10 min at a sub-boiling temperature (95°-98°C). Cool slides on bench top for 30 min.

D. Staining

  1. Wash sections in dH2O three times for 5 min each.
  2. Incubate sections in 3% hydrogen peroxide for 10 min.
  3. Wash sections in dH2O two times for 5 min each.
  4. Wash sections in wash buffer for 5 min.
  5. Block each section with 100–400 µl of preferred blocking solution for 1 hr at room temperature.
  6. Remove blocking solution and add 100–400 µl primary antibody diluted in SignalStain® Antibody Diluent (#8112) to each section. Incubate overnight at 4°C.
  7. Equilibrate SignalStain® Boost Detection Reagent (HRP, Mouse #8125) to room temperature.
  8. Remove antibody solution and wash sections with wash buffer three times for 5 min each.
  9. Cover section with 1–3 drops SignalStain® Boost Detection Reagent (HRP, Mouse #8125) as needed. Incubate in a humidified chamber for 30 min at room temperature.
  10. Wash sections three times with wash buffer for 5 min each.
  11. Add 1 drop (30 µl) SignalStain® DAB Chromogen Concentrate to 1 ml SignalStain® DAB Diluent and mix well before use.
  12. Apply 100–400 µl SignalStain® DAB to each section and monitor closely. 1–10 min generally provides an acceptable staining intensity.
  13. Immerse slides in dH2O.
  14. If desired, counterstain sections with hematoxylin (#14166).
  15. Wash sections in dH2O two times for 5 min each.
  16. Dehydrate sections:
    1. Incubate sections in 95% ethanol two times for 10 sec each.
    2. Repeat in 100% ethanol, incubating sections two times for 10 sec each.
    3. Repeat in xylene, incubating sections two times for 10 sec each.
  17. Mount sections with coverslips and mounting medium (#14177).

Protocol Id: 280

Specificity / Sensitivity

Thyroid Transcription Factor 1 (TTF-1) (SPT24) Mouse mAb recognizes endogenous levels of TTF-1 protein.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a recombinant protein corresponding to a 123 amino acid fragment of the N-terminal region of human TTF-1 protein.

Background

Thyroid Transcription Factor 1 (TTF-1, also known as NKX2-1), a member of the NKX homeobox transcription factor family, was initially discovered in the FRTL-5 rat thyroid cell line (1). Subsequent studies have shown that TTF-1 plays an important role in differentiation and morphogenesis of the developing thyroid, lung, and ventral forebrain (2). TTF-1 controls the expression of several genes, some of which are tissue specific, such as: thyroglobulin, thyroperoxidase, and the thyrotropin receptor in the thyroid; and surfactant proteins and clara cell secretory protein in the lung (2,3). Investigators have found that TTF-1 is expressed in malignant tumors of the thyroid and lung, and it is commonly used as a marker for both primary and malignant lung cancers (4-6).
