      Alexa Fluor® 647 Mouse Anti-ERK1/2 (pT202/pY204)
      Alexa Fluor® 647 Mouse Anti-ERK1/2 (pT202/pY204)
      Flow cytometric analysis of ERK1/2 (pT202/pY204). Human peripheral blood mononulcear cells (PBMC) were either left unstimulated (unshaded) or stimulated (shaded) with 40 nM PMA for 10 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-ERK1/2 (pT202/pY204) antibody. Cells were analyzed on a BD FACSCalibur™ flow cytometry instrument. For intracellular staining of human whole blood, BD™ Phosflow Lyse/Fix buffer (Cat. No. 558049) may be used for fixation.

      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.

      20A

      The members of the Mitogen-Activated Protein Kinase (MAPK) family are components of a key signal transduction cascade that links events at the cell surface to responses in the nucleus. The signaling cascade is found in species as varied as yeast and humans, with many of the proteins being well conserved. In mammals the most widely studied members of the cascade are the Extracellular signal-Regulated Kinases, ERK1 (p44 MAPK) and ERK2 (p42 MAPK).  ERK1 and ERK2 share 85% homology and are activated by extracellular signals such as growth factors, hormones, and phorbol esters. Activation occurs through a series of phosphorylations by kinases activating other kinases and eventually leading to phosphorylation of the ERKs. Growth factor stimulation leads to activation of Ras and Raf, leading to phosphorylation of MEK1 (MAPK/ERK kinase) which, in turn, activates the ERKs via dual phosphorylation. Once activated, the ERKs phosphorylate other cytoplasmic signalling molecules, cell-surface receptors, microtubule-associated proteins, and transcription factors in the nucleus. Thus, the active ERK has myriad downstream effectors that implicate it in the control of cell proliferation and differentiation, as well as regulation of the cytoskeleton. Furthermore, studies have shown that elevated ERK activity is associated with some cancers.

      The 20A monoclonal antibody recognizes the phosphorylated threonine 202 and tyrosine 204 (pT202/pY204) of human ERK1 and pT184/pY186 of human ERK2. The orthologous phosphorylation sites in murine ERK1 and ERK2 are T203/Y205 and T183/Y185.

      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.
