RB545 Mouse Anti-Human CD69
RB545 Mouse Anti-Human CD69
Flow cytometric analysis of CD69 expression on stimulated Human peripheral blood mononuclear cells. Human peripheral blood mononuclear cells (PBMC) were stimulated for 24 hours with Phytohemagglutinin (PHA).  The cells were then stained with either BD Horizon™ RB545 Mouse IgG1, κ Isotype Control (Cat. No. 569284; dashed line histogram) or BD Horizon™ RB545 Mouse Anti-Human CD69 antibody (Cat. No. 569273/569274; solid line histogram). The fluorescence histogram showing CD69 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable activated lymphocytes.  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. 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.
  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.
  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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  6. An isotype control should be used at the same concentration as the antibody of interest.
  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.

FN50

The FN50 monoclonal antibody specifically binds to human CD69. CD69 is also known as activation-induced molecule (AIM), early activation antigen (EA-1), very early activation antigen (VEA), C-type lectin domain family 2 member C (CLEC2C), MLR-3, GP32/28 and Leu-23. CD69 is a transmembrane type II homodimer receptor. CD69 is comprised of disulfide-linked, differentially glycosylated core protein subunits that are approximately 28 and 34 kDa in size. Each subunit contains a C-type lectin domain.  CD69 is expressed on activated T, B, and natural killer (NK) lymphocytes, thymocytes, neutrophils, eosinophils and platelets. In normal peripheral blood, a small and variable percentage of lymphocytes typically express detectable membrane CD69 antigen. Upon activation, CD69 antigen expression increases on lymphocytes. Peak CD69 expression generally occurs within 18 hours of activation, preceding the appearance of HLA-DR, IL-2Rα (CD25) and transferrin receptor (CD71). CD69 is highly expressed on the bright CD3+ subset of thymocytes. FN50 monoclonal antibody labels NK cells and most lymphocytes of the follicular mantle and perifollicular/interfollicular zone as well as germinal center T cells of lymph nodes and tonsils. Studies indicate that CD69 serves as a signaling receptor in the activation of a variety of cell types.

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.
