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™ PE-CF594 Mouse IgG2a, κ Isotype Control (Cat. No. 563484; Left Plot) or BD Horizon™ PE-CF594 Mouse Anti-Human IL-22 antibody (Cat. No. 567566/567565; Right Plot) at 0.015 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
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
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- An isotype control should be used at the same concentration as the antibody of interest.

- When excited by the yellow-green (561-nm) laser, the fluorescence may be brighter than when excited by the blue (488-nm) laser.

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).
This antibody is conjugated to BD Horizon™ PE-CF594, which has been developed exclusively by BD Biosciences as a better alternative to PE-Texas Red®. PE-CF594 excites and emits at similar wavelengths to PE-Texas Red® yet exhibits improved brightness and spectral characteristics. Due to PE having maximal absorption peaks at 496 nm and 564 nm, PE-CF594 can be excited by the blue (488-nm), green (532-nm) and yellow-green (561-nm) lasers and can be detected with the same filter set as PE-Texas Red® (eg, 610/20-nm filter).
