Product Highlight

FIX&PERM Cell Fixation and Permeabilization Kit

Flow cytometric analyses with monoclonal antibodies were so far mainly restricted to cell surface molecules. Intracellular structures such as cytoplasmic or nuclear enzymes, oncoproteins, cytokines, immunoglobulins etc. were largely excluded from such studies. Also excluded from flow cytometric studies were cytoplasmic localizations of well-established membrane molecules like CD3 and CD22, which, in their cytoplasmic form, are the most reliable lineage markers in undifferentiated leukemia. With the FIX&PERM® Kit flow cytometric analysis of intracellular antigens has become as easy as surface antigen studies. The only prerequisite is the availability of suitable antibody conjugates. Most of the available monoclonal antibody conjugates can be used with the FIX&PERM® Kit, some determinants are sensitive, however, to the fixation step involved. This and the optimal fixation time have to be tested for each reagent.

Akt, also known as Protein Kinase B (PKB) or RAC- , 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-3 , 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.
