Flow cytometric analysis of BAFF (BLyS/CD257) expression on human U937 cells. Cells from the human U937 (Histiocytic Lymphoma, ATCC CRL-1593.2) cell line were stained with PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; dashed line histogram) or PE Mouse Anti-BAFF (BLyS/CD257) antibody (Cat. No. 567738; solid line histogram) at 1 μg/test. DAPI (4',6-Diamidino-2-Phenylindole, Dihydrochloride) Solution (Cat. No. 564907) was added to cells right before analysis. The fluorescence histogram showing BAFF (BLyS/CD257) expression (or Ig Isotype control staining) was derived from gated events with the light-scatter characteristics of viable (DAPI-negative) cells. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X20 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

推荐的实验流程
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.

- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- 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.

The H32-411 monoclonal antibody specifically recognizes B-cell activating factor (BAFF) which is also known as B-lymphocyte stimulator protein (BLyS), TNF and ApoL-related leukocyte expressed ligand 1 (TALL1), Dendritic cell-derived TNF-like molecule (DTL) and CD257. BAFF is a type II transmembrane glycoprotein that is encoded by TNFSF13B (TNF superfamily member 13b). BAFF can be expressed on B cells, macrophages, and dendritic cells as well as on tumor cells. Membrane and soluble forms of BAFF have been described. In its soluble form, BAFF can serve as a potent B cell growth factor in costimulation assays, suggesting its biological role in monocyte-driven B cell activation. BAFF has also been linked to B cell hyperplasia and autoimmunity.
