      Alexa Fluor® 647 Mouse anti-PKA[RIIβ] (pS114)
      Alexa Fluor® 647 Mouse anti-PKA[RIIβ] (pS114)
      Analysis of PKA[RIIβ] (pS114) in human peripheral blood lymphocytes.  Human peripheral blood mononuclear cells (PBMC) were either treated with 1μM Staurosporine (EMD Biosciences, Cat. No. 569397) for 2hours at 37ºC (shaded histogram) or untreated (open histogram).  The PBMC were fixed (BD Cytofix™ buffer, Cat. No. 554655) for 10 minutes at 37°C, permeabilized with BD Phosflow™ Perm Buffer III (Cat. No. 558050) on ice for 30 minutes, and then stained with Alexa Fluor® 647 Mouse anti-PKA[RIIβ] (pS114, Cat. No. 560205).  For data analysis, lymphocytes were selected by their scatter profile.  The data demonstrates that the level of phosphorylation of PKA[RIIβ] decreases when protein kinase activity is inhibited by the treatment.  Flow cytometry was performed on a BD FACSCalibur™ flow cytometry 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 to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was 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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      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. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
      5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      6. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.

      47/PKA

      cAMP-dependent Protein Kinase (PKA) is composed of two distinct subunits: catalytic (C) and regulatory (R).  Four regulatory subunits have been identified: RIα, RIβ, RIIα, and RIIβ.  These subunits define type I and II PKAs.  Following binding of cAMP, the regulatory subunits dissociate from the catalytic subunits, rendering the enzyme active.  Type I and type II holoenzymes have three potential C subunits (Cα, Cβ, or Cγ).  Most cells, including T lymphocytes, express both type I and type II PKAs.  RIIα expression is associated with cellular transformation, while RIIβ expression correlates with mitotic arrest and cellular differentiation.  Type II PKA can be distinguished by autophosphorylation of the R subunits, while type I PKA binds Mg/ATP with high affinity. The cAMP-dependent autophosphorylation of the human RIIβ subunits occurs at serine 114 (S114).  In addition to their enzyme regulatory activity, the RIIα and RIIβ subunits determine the subcellular location of the holoenzymes via their interactions with specific intracellular anchoring proteins.

      The 47/PKA monoclonal antibody recognizes the phosphorylated S114 in the RIIβ subunit of PKA.  The orthologous phosphorylation site in mouse and rat PKA[RIIβ] is S112.

      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 520-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.
