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
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.

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™ Red 718, which has been developed exclusively by for BD Biosciences as a better alternative to Alexa Fluor™ 700. BD Horizon™ Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor™ 700.
