      PE Mouse Anti-Human IRF1
      PE Mouse Anti-Human IRF1
      Flow cytometric analysis of IRF1 expressed in  HeLa cells. Cells from the human HeLa (Cervical adenocarcinoma, ATCC CCL-2) cell line were either cultured overnight in complete tissue culture medium without (Left Panel) or with (Right Panel) Recombinant Human IFN-γ protein (10 ng/ml; Cat. No. 554617). The cells were harvested, fixed and permeabilized using the BD Pharmingen Transcription Factor Buffer Set (Cat. No. 562574/562725). The cells were then stained with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; dashed line histograms) or PE Mouse Anti-Human IRF1 antibody (Cat. No. 566322; solid line histograms) at 0.5 µg/test. Data shown on this Technical Data Sheet are not lot specific. The fluorescence histograms showing IRF1 expression (or Ig Isotype control staining), were derived from gated events with the forward and side light-scatter characteristics of intact HeLa cells. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Flow Cytometer System.

      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 with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. An isotype control should be used at the same concentration as the antibody of interest.
      3. 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.
      4. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

      20/IRF-1

      The 20/IRF-1 monoclonal antibody specifically binds to Interferon regulatory factor 1 (IRF1). IRF1 belongs to the human IRF family of transcription factors that contains nine members, IRF1-9. IRF1 is broadly expressed and its levels are upregulated in response to certain cytokines, interferons, bacterial or viral infections. IRF1 binds to specific DNA motifs such as IFN-stimulated response elements (ISRE) and regulates the activity of IFN-responsive genes. IRF1 plays roles in inflammation as well as innate and adaptive immune responses. It is involved in the regulation of cellular proliferation, Major Histocompatibility Complex (MHC) antigen expression, and the differentiation and effector functions of macrophages, dendritic cells, natural killer (NK) cells, and various T cell subsets. In addition, IRF1 may function as a tumor suppressor, since deletions in the IRF1 locus is associated with myelodysplasia and leukemias.

      PE
      R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
