Purified Mouse Anti-Human Ki-67

Western blot analysis of Ki-67 on a HeLa lysate (Cat. No. 611449). Lane 1: 1:250, lane 2: 1:500, lane 3: 1:1000 dilution of the Ki-67 antibody.

Purified Mouse Anti-Human Ki-67

Immunofluorescent staining of U-2 OS (ATCC HTB-96) cells. Cells were seeded in a 96 well imaging plate (Cat. No. 353219) at ~ 10 000 cells per well.  After overnight incubation, cells were stained using the Triton™ X-100 perm protocol and the anti-Ki-67 antibody.  The second step reagent was FITC goat anti mouse Ig (Cat. No. 554001).  The image was taken on a BD Pathway™ 855 Bioimager using a 20x objective.  This antibody also stained HeLa (ATCC CCL-2) and A549 (ATCC CCL-185) cells and can be used with either perm protocol (see Recommended Assay Procedure).

Recommended Assay Procedures

Bioimaging

1. Seed the cells in appropriate culture medium at ~10,000 cells per well in a BD Falcon™ 96-well Imaging Plate (Cat. No. 353219) and culture overnight.

2. Remove the culture medium from the wells, and fix the cells by adding 100 μl of BD Cytofix™ Fixation Buffer (Cat. No. 554655) to each well.  Incubate for 10 minutes at room temperature (RT).

3. Remove the fixative from the wells, and permeabilize the cells using either BD Perm Buffer III, 90% methanol, or Triton™ X-100:

a. Add 100 μl of -20°C 90% methanol or Perm Buffer III (Cat. No. 558050) to each well and incubate for 5 minutes at RT.

     OR

b. Add 100 μl of 0.1% Triton™ X-100 to each well and incubate for 5 minutes at RT.

4. Remove the permeabilization buffer, and wash the wells twice with 100 μl of 1× PBS.

5. Remove the PBS, and block the cells by adding 100 μl of BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656) to each well. Incubate for 30 minutes at RT.

6. Remove the blocking buffer and add 50 μl of the optimally titrated primary antibody (diluted in Stain Buffer) to each well, and incubate for 1 hour at RT.

7. Remove the primary antibody, and wash the wells three times with 100 μl of 1× PBS.

8. Remove the PBS, and add the second step reagent at its optimally titrated concentration in 50 μl to each well, and incubate in the dark for 1 hour at RT.

9. Remove the second step reagent, and wash the wells three times with 100 μl of 1× PBS.

10. Remove the PBS, and counter-stain the nuclei by adding 200 μl per well of 2 μg/ml Hoechst 33342 (e.g., Sigma-Aldrich Cat. No. B2261) in 1× PBS to each well at least 15 minutes before imaging.

11. View and analyze the cells on an appropriate imaging instrument.

35/Ki-67

Cellular proliferation is a complex multi-faceted process, central to biological events ranging from embryonic development to wound healing. Although proliferation is tightly controlled, dysregulation often results in tumorigenesis. The regulatory process involves the expression of many cell-cycle-associated proteins that are subject to cycle-dependent modification. Such protein expression may be monitored to assess the proliferative capacity of cells, especially tumorigenic cells.The Ki-67 antigen is a nuclear protein expressed exclusively in proliferating cells during all active parts of the cell cycle. However, it is absent in quiescent cells and during DNA repair. The distribution of Ki-67 changes during different stages of the cell cycle. During G1, it is localized to the perinuclear region, but is primarily found in the nuclear matrix in later phases. During mitosis, it associates with the condensed chromosomes. The nuclear localization of Ki-67 and strict association with the cell cycle indicate its importance in the regulation of cell division. Therefore, Ki-67 has become an important marker of proliferating cells, and may also be a marker for disitinct nuclear matrix compartments.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
