RB780 Mouse Anti-Ki-67
RB780 Mouse Anti-Ki-67
Two-color flow cytometric analysis of Ki-67 expression by noncycling Human peripheral blood lymphocytes or proliferating Human MOLT-4 cells. Noncycling Human peripheral blood mononuclear cells (PBMC; Top Plots) or proliferating cells from the Human MOLT-4 (T lymphoblastic leukemia, 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™ RB780 Mouse IgG1 Isotype Control (Cat. No. 568532; Left Plots) or BD Horizon™ RB780 Mouse Anti-Ki-67 antibody (Cat. No. 568761/568762; 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 expression (or Ig isotype Control staining) were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes or MOLT-4 cells. Flow cytometry and data analysis were performed using a BD FACSymphony™ A5 SE Cell Analyzer System and FlowJo™ Software.

准备和存储

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.

推荐的实验流程

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.

商品通知

  1. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  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. 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.
  5. 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).
  6. An isotype control should be used at the same concentration as the antibody of interest.
  7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  8. 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.

RB780
The BD Horizon RealBlue™ 780 (RB780) Dye is part of the BD family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 781-nm. Driven by BD innovation, RB780 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB780 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-Cy7. RB780 is on average brighter than PE-Cy7 and has minimal spillover into Yellow-Green detectors.
