    R718 Mouse Anti-Ki-67
    R718 Mouse Anti-Ki-67
    Two-color flow cytometric analysis of Ki-67 expression by noncycling human peripheral blood mononuclear cells or proliferating MOLT-4 cells. Noncycling human peripheral blood mononuclear cells (PBMC; Top Plots) or proliferating cells from the human MOLT-4 (ATCC CRL-1582) cell line (Bottom Plots) were permeabilized and fixed with 70% ice-cold ethanol. The cells were washed twice with BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656), stained with either BD Horizon™ R718 Mouse IgG1 Isotype Control (Cat. No. 566928; Left Plots) or BD Horizon™ R718 Mouse Anti-Ki-67 antibody (Cat. No. 566963; Right Plots) and counterstained with BD Pharmingen™ DAPI Solution (Cat. No. 564907) to stain DNA. Bivariate pseudocolor density plots showing the correlated expression of DAPI staining versus Ki-67 (or Ig isotype Control staining) were derived from gated events with the forward and side light-scatter characteristics of intact PBMC or MOLT-4 cells. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software.

    Preparation And Storage

    Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

    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 cells and BD CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

    Product Notices

    1. 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).
    2. An isotype control should be used at the same concentration as the antibody of interest.
    3. 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.

    B56

    The B56 monoclonal antibody specifically binds to the Ki-67 antigen that is expressed in the nucleus of cycling cells (G1, S, G2, M cell cycle phases). During the G0 phase, the antigen cannot be detected. During interphase of the cell cycle, it is associated with nucleolar components, and it is on the surface of the chromosomes during M phase. Ki-67 is a large protein having 2 alternatively spliced isoforms, an N-terminal forkhead-associated domain, a C-terminal domain that binds to heterochromatin proteins, and multiple phosphorylation sites, the functions of which are still unclear. Because of the strict association of Ki-67 expression with cell proliferation, anti-Ki-67 antibodies are useful for the identification, quantification, and monitoring of growing cell populations.

    The antibody was conjugated to BD Horizon™ Red 718, which has been developed exclusively by for BD Biosciences as a better alternative to Alexa Fluor™ 700. BD Horizon™ Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor™ 700.

    R718
    The BD Horizon™ Red 718 (R718) Dye is part of the BD red family of dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 695-nm and an emission maximum (Em Max) at 718-nm. Driven by BD innovation, R718 is designed to be excited by the red laser (627–640-nm) and detected using an optical filter centered near 720-nm (e.g., a 720/40-nm bandpass filter). R718 is a brighter alternative to Alexa Fluor™ 700. R718 is also a bright small molecule alternative to APC-R700 with lower spread into the APC detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
