Formulation:Liquid. In Tris buffer, pH 7.5, containing 1% BSA and <0.1% sodium azide.
 
Use/Stability:When stored correctly, the antibody is stable until the date indicated on the label. To ensure proper stability of the antibody after each run, replace the cap and immediately place the bottle in a refrigerator in an upright position.
 
Handling:Avoid freeze/thaw cycles.
 
Shipping:Shipped on Blue Ice
 
Long Term Storage:+4°C
 
Scientific Background:Ki-67 is a nuclear, non-histone protein that is expressed only during active phases of the cell cycle (G1, S, G2 and M), but not in the resting phases (G0 and G1 early phase). Although the antigen has also been associated with ribosomal RNA transcription, it is strongly linked to cell proliferation and has thus been indicated as an effective marker in grading the proliferation rate of tumors, including those of the brain, breast, cervix, and prostate.
 
Protocol:Manual Use
  1. Antigen Retrieval: Perform antigen retrieval with Antigen Retrieval Reagent, pH 9 (ENZ-ACC113), for 10 to 30 minutes at 100°C.
  2. Peroxidase Block: Block using IHC/ISH Peroxidase Block (ENZ-ACC107) for five minutes at room temperature.
  3. Primary Antibody: Dilute antibody 1:100-1:200 before applying 150 µL directly to the tissue. Incubate for 10 to 30 minutes at room temperature.
  4. Secondary Antibody: Incubate using POLYVIEW® PLUS (anti-Mouse) HRP Reagent (ENZ-ACC104) or POLYVIEW® PLUS (anti-Mouse) AP Reagent (ENZ-ACC114) for 20 to 30 minutes.
  5. Substrate Development: Incubate using HIGHDEF® DAB Substrate/Chromogen (ENZ-ACC105) for 5 to 10 minutes at room temperature.
  6. Counterstain: Counterstain with hematoxylin for 30 seconds to 5 minutes. Rinse with distilled water.

Automated Staining
For automated staining, we recommend incubating for 30 minutes with the primary antibody and using Antigen Retrieval at pH 9 for 30 minutes.
