Mouse anti-M13 phage coat protein g8p

Antibodies recognising M13 filamentous phage coat proteins are instrumental in the selection and detection of phages expressing specific antibody fragments or peptide sequences at their surface. The monoclonal antibodies manufactured and supplied by Exalpha react with either the pIII (g3p) or pVIII (g8p) proteins of M13 filamentous bacteriophage. All antibodies are available in a purified format. The antibodies are fully validated and are suitable for a wide range of techniques including:

  • Flow Cytometry
  • Western Blot
  • Immunohistochemistry
  • Immunoprecipitation

Akt, also known as Protein Kinase B (PKB) or RAC-α, is a 65 kDa serine/threonine kinase that plays an important role in diverse biological responses such as regulation of metabolism, cell survival and growth by phosphorylating many proteins including GSK-3β, caspase 9, BAD and the Forkhead Transcription Factor. Akt is activated by PI3K, which in turn can interact with proteins such as FAK (when FAK is phosphorylated at tyrosine 397) thereby linking activation to the cytoskeleton. Akt is phosphorylated on threonine 308 by PDK1 and on serine 473 by PDK2. Phosphorylation at serine 473 is required for full activation of Akt.


Chemically synthesized phosphopeptide derived from the region of human Akt that contains serine 473.

Image Legend

Immunofluorescence Staining Serum-starved NIH3T3 cells left untreated (left) or treated with PDGF (right) were fixed prior to immunostaining with the Akt [pS473] rabbit monoclonal antibody. The signal was detected with an anti-rabbit FITC conjugated secondary antibody. The data show that the antibody detected phosphorylated Akt in PDGF-treated NIH3T3 cells. Cells were counterstained with DAPI. Please visit our website (biosource.com) to view the images in full color.
