RB545 Mouse Anti-Ki-67
RB545 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™ RB545 Mouse IgG1 Isotype Control (Cat. No. 569284; Left Plots) or BD Horizon™ RB545 Mouse Anti-Ki-67 antibody (Cat. No. 569275/569276; Right Plots) and counterstained with DAPI (4',6-Diamidino-2-Phenylindole, Dihydrochloride) 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. Samples were acquired on the BD FACSymphony™ A5 SE Cell Analyzer and spectrally unmixed using FlowJo™ v10.8 Software.

Preparation And Storage

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

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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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.
  3. Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
  4. 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).
  5. An isotype control should be used at the same concentration as the antibody of interest.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  7. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
  8. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
  9. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

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.

RB545
The BD Horizon RealBlue™ 545 (RB545) fluorochrome is part of the BD family of blue (488-nm) laser dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 496-nm and an emission maximum (Em Max) at 545-nm. Driven by BD innovation, RB545 can be used on spectral cytometers and is designed to be excited by the blue (488-nm) laser with minimal excitation by the 561-nm yellow-green laser. RB545 has minimal spillover into yellow-green detectors and a brightness level similar to FITC.  Given its unique emission max, on a spectral instrument RB545 can be used simultaneously with FITC and PE to provide an additional color off of the blue laser. Please ensure that your instrument configuration (lasers and optical filters) is appropriate for this dye.
