The Ki67 antibody is considered a nuclear protein, expressed in almost all proliferating cells. It is primarily expressed during late S, G1, M, and G2 phases of the cell’s cycle, though cells in the quiescent phase are negative. This product is for research purposes only and shouldn’t be used for diagnostics or other procedures. It has no clone, and the immunogen is the synthetic peptide that is derived from the c-terminus of the protein.

The isotype is the Rabbit IgG with an undetermined epitope. Likewise, the molecular weight is 345 and 395 kDa.


The Ki67 antibody is designed for Immunohistochemistry applications. To prepare your specimens, you should use formalin-fixed or paraffin-embedded tissues. Likewise, deparaffinized slides are necessary and should be cleaned with xylene or its alternative.

You can find a pre-diluted formula for this antibody. However, you can also find concentrated versions. If you choose to use the concentrate, you will need to dilute it using a ratio of 1:300.

To retrieve the antigen, it is best to boil the tissue sections using a 10mM citrate buffer with a pH of 6.0. This should be done for 10 minutes, allowing the antigen to cool to room temperature for 20 minutes. Likewise, it will need to incubate for at least 10 minutes while at room temperature. You should wash the slides between each step. You can rinse them with PBS-Tween.

Positive controls for the Ki67 antibody include the lymph node, breast carcinoma, and tonsil. Cellular localization is in the nucleus.
