BV421 Mouse Anti-Human IL-22
Multicolor 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 BD Horizon™ BUV395 Mouse Anti-Human CD4 (Cat. No. 564724) and either BD Horizon™ BV421 Mouse IgG2a, κ Isotype Control (Cat. No. 563464; Left Panel) or BD Horizon™ BV421 Mouse Anti-IL-Human 22 antibody (Cat. No. 567765/567793; Right Panel) at 0.125 µg/test. Bivariate pseudocolor density plots showing the correlated expression of IL-22 (or Ig Isotype control staining) versus CD4 were 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 X-20 LSRFortessa™ Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

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 unconjugated antibody and free dye were 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.

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 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).

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).

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max near 407 nm and Em Max near 421 nm, BD Horizon™ BV421 can be excited by the violet laser (405 nm) and detected with a 450/50 nm filter. BD Horizon™ BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon™ BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
