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.


Welcome, Peter Rutten

We are pleased to announce that Peter Rutten has now started in his role as Operations Director here at Exalpha Biologicals Inc. Peter has a Master’s of Science degree in Industrial and Organizational Psychology and this has lead him down a very business orientated career path. Peter is looking forward to working with the team at Exalpha. Peters primary focus is the customer experience and he will be working with the Laboratory team, the Quality Control team and the Order Processing team to ensure this focus is achieved. We all wish Peter well in his new role.

Akt, also known as Protein Kinase B (PKB) or RAC- , is a 60 kDa serine/threonine kinase that plays an important role in multiple biological responses including 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 like FAK thereby linking activation to the cytoskeleton. Akt/PKB is constitutively active in many types of human cancer, and contributes to tumor progression by promoting angiogenesis and cell invasiveness. Akt is fully activated by phosphorylation of threonine 308 by PDK1 and serine 473 by PDK2.


A synthetic peptide derived from the caraboxy-terminus region of human Akt1

Image Legend

Extracts of 3T3L1 cells were resolved by SDS-PAGE on a 10% Tris-glycine gel and transferred to PVDF. The membrane was blocked with a 5% BSA-TBST buffer for one hour at room temperature, then incubated with a 1:1000 (1) or 1:500 (2) dilution of the Akt/PKB pan antibody for two hours at room temperature in a 3% BSA-TBST buffer. After washing, the membrane was incubated with goat F(ab?)2 anti-rabbit IgG HRP-conjugate and signals were detected using the Pierce SuperSignal™ method.
