Flow cytometric analysis of Stat1 (pY701).  U-937 cells (Human histiocytic lymphoma; ATCC CRL-1593.2) were either left unstimulated (unshaded) or stimulated (shaded) with 1000 U/mL recombinant human IFN-γ (Cat. No. 554617) for 15 minutes at 37°C. Cells were fixed with BD Cytofix™ buffer (Cat. No. 554655) for 10 minutes at 37°C and then permeabilized by adding BD Phosflow™ Perm Buffer III (Cat. No. 558050 for 30 minutes on ice. Cells were then washed twice in BD Pharmingen™ Stain Buffer (Cat. No. 554656) and stained with the Alexa Fluor® 647 mouse anti-Stat1 (pY701) antibody. Cells were analyzed on a BD FACSCalibur™ flow cytometery instrument. For intracellular staining of human whole blood, BD Phosflow™ Lyse/Fix buffer (Cat. No. 558049) may be used for fixation.

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.

  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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
  4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  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.

4a

Stat (Signal transducer and activators of transcription) proteins mediate the biological activity of cytokines, including interleukins, interferons, erythropoietin, and growth factors.  Ligand-receptor interaction activates constitutively-associated JAK family kinases as well as subsequent recruitment and activation of Stat proteins by tyrosine phosphorylation.  Active Stat proteins then move to the nucleus to promote transcription of cytokine-inducible genes.  Seven Stat proteins have been cloned, each of which is differentially expressed and/or activated in a cytokine-specific and cell type-specific manner.  Stat1 and Stat2 are components of the ISGF3 (Interferon-Stimulated Gene Factor 3) complex, the primary transcription activator induced by interferon binding to a specific cell-surface receptor.  Stat1 has two alternatively spliced isoforms, 91-kDa Stat1α and 84-kDa Stat1β; Stat1α has 38 additional C-terminal amino acids.  In response to the binding of IFNα, IFNγ, EGF, PDGF, or CSF-1 to their respective receptors, the Stat1 subunits become tyrosine-phosphorylated at Y701, and the complex translocates to the nucleus. This forms an active complex that includes the DNA-binding p48 subunit, and is responsible for modulating interferon-stimulated genes (ISGs) transciption.

The 4a monoclonal antibody recognizes the phosphorylated Y701 in Stat1α and Stat1β.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor™ 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 670-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
