Preparation And Storage
Recommended Assay Procedures
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- An isotype control should be used at the same concentration as the antibody of interest.

The Ki-67 monoclonal antibody specifically recognizes the Ki-67 antigen (also known as KI67, KI-67). Ki-67 is a nonhistone nuclear protein that is encoded by MKI67 (Marker of Proliferation Ki-67). Ki-67 is associated with cellular proliferation and its expression increases as cells enter and progress through the G1, S, G2, and M cell cycle phases. Ki-67 is a large protein having 2 alternatively spliced isoforms. The Ki-67 protein contains an N-terminal forkhead-associated domain, a protein phosphatase 1-binding domain, a large central region of tandem repeats, and a C-terminal leucine/arginine-rich chromatin-binding domain. Ki-67 is required for cell proliferation and serves as useful marker for distinguishing and analyzing quiescent cells (Ki-67-negative cells within the G0 cell cycle phase) from cycling Ki-67-positive cells including cancer cells.
