      PE Mouse Anti-Human Leukemia Inhibitory Factor
      PE Mouse Anti-Human Leukemia Inhibitory Factor
      Expression of intracellular LIF by in-vitro-activated human peripheral blood cells. Human peripheral blood mononuclear cells (HPBMC) isolated by density gradient centrifugation (Ficoll-Paque™) were stimulated with plate-bound anti-human CD3 antibody (10 µg/ml, Cat. No. 555336) and soluble anti-CD28 antibody (2 µg/ml, Cat. No. 555725) in the presence of human IL-2 (10 ng/ml, Cat. No. 554603) and IL-4 (40 ng/ml, Cat. No. 554605) for 2 days. The cells were subsequently washed and expanded in IL-2 and IL-4 for 3 days. Following expansion, the cells were washed and stimulated for 5 hrs with PMA (5 ng/ml) and ionomycin (500 ng/ml) in the presence of BD GolgiPlug™ (Cat. No. 555029). Following incubation, the cells were harvested, washed and fixed with BD Cytofix/Cytoperm™ Solution (Cat. No. 554722, 15 min, 4°C). The intracellular levels of LIF expressed by activated HPBMC were detected by immunofluorescent staining and flow cytometric analysis using the PE-conjugated 1F10 antibody (left panel, 20 µl/10e6 cells, Cat. No. 558571) or an immunoglobulin isotype control (right panel). Dot plots (left and right panels) were derived from gated events with the forward- and side- light scatter characteristics of mononuclear cells.

      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. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
      2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      4. Ficoll-Paque is a trademark of Amersham Biosciences Limited.
      5. 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.
      6. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      8. An isotype control should be used at the same concentration as the antibody of interest.

      1F10

      The 1F10 antibody specifically binds to human Leukemia Inhibitory Factor (LIF) also known as Human Interleukin for DA cells (HILDA), Melanoma-derived Lipoprotein Lipase Inhibitor (MLPLI) and Hepatocyte Stimulating Factor III (HSF III). LIF is produced by multiple sources including activated T cells and macrophages, myelomonocytic lineages, fibroblasts, liver, heart and melanoma cells. LIF regulates the differentiation of embryonic stem cells, neural cells, osteoblasts, adipocytes, hepatocytes and kidney epithelial cells. Other activities include terminal differentiation in leukemic cells and the stimulation of acute-phase protein synthesis in hepatocytes. Many of its biological functions parallel those of Interleukin-6, Oncostatin M, Ciliary Neurotrophic Factor, Interleukin-11 and Cardiotrophin-1. In vivo LIF is important in regulating the inflammatory response by tuning the balance of four systems in the body, namely the immune, the haematopoietic, the nervous and the endocrine systems. The immunogen used to generate the 1F10 hybridoma was recombinant vaccinia virus encoding the human LIF cytokine. The LIF cytokine had been engineered to get expressed on the membrane of the infected cell. The attachment to the membrane was obtained with the glycosylphoshosphatidyl anchor targeting DNA sequence from the DAF molecule (CD55).

      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.
