BUV737 Mouse Anti-Human IL-22
BUV737 Mouse Anti-Human IL-22
Two-color flow cytometric analysis of IL-22 expression in Human peripheral blood mononuclear cells (PBMCs).  PBMCs were cultured in complete tissue culture medium with Phorbol 12-Myristate 13-Acetate (PMA; Sigma, 50 ng/ml) and Ionomycin (Sigma, 500 ng/ml) in the presence of BD GolgiPlug™ Protein Transport Inhibitor (Cat. No. 555029) for 6 hours. The cells were harvested, then fixed and permeabilized using BD Cytofix™ Fixation Buffer (Cat. No. 554655) and BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained with APC Mouse Anti-Human CD4 antibody (Cat. No. 561841) and with either BD Horizon™ BUV737 Mouse IgG2a, κ Isotype Control (Cat. No. 612765; Left Plot)) or BD Horizon™ BUV737 Mouse Anti-Human IL-22 antibody (Cat. No. 569641/569642; Right Plot). The bivariate pseudocolor density plot showing the correlated expression of IL-22 (or Ig Isotype control staining) versus CD4 was derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ Software.

Preparation And Storage

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 unconjugated antibody and free dye were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

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.

    For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

Note:  When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed.  For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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).
  3. An isotype control should be used at the same concentration as the antibody of interest.
  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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  6. 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.

MH22B2

The MH22B2 monoclonal antibody specifically recognizes human Interleukin-22 (IL-22), which is encoded by the IL22 gene. Cross-reactivity of MH22B2 mAb to mouse IL-22 (which shares 79% amino acid identity with human IL-22) has been observed by ELISA and by flow cytometry of HEK293 cells transfected with mouse IL-22 and TH17-differentiated CD4-positive T cells from C57BL/6 mice. IL-22 (with or without other cytokines) is secreted by many T-cell and innate-lymphoid-cell populations. Evidence that IL-22 plays a key role in mucosal immunity includes the restricted expression of the alpha subunit of the heterodimeric IL-22 receptor, called IL-22R1, on epithelial cells and cells of epithelial origin. At epithelial surfaces, IL-22 elicits antimicrobial defenses and maintains epithelial integrity. Alternatively, uncontrolled IL-22 production can result in certain inflammatory disorders. Regulation of IL-22 expression is complex, involving other cytokines (eg, IL-6, IL-23, and TGF-β) and many transcription factors, (eg, AHR, c-Maf, STAT3, RORɤT, BATF, and others).

BUV737
The BD Horizon Brilliant™ Ultraviolet 737 (BUV737) Dye is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This tandem fluorochrome is comprised of a BUV395 donor with an excitation maximum (Ex Max) of 350-nm and an acceptor dye with an emission maximum (Em Max) at 735-nm. BUV737, driven by BD innovation, is designed to be excited by the ultraviolet laser (355-nm) and detected using an optical filter centered near 740-nm (e.g., 740/35 bandpass filter). The acceptor dye can be excited by the Red (628–640nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
