![]() M., An Integrated View of Immunometabolism. (B) Calculated total fluorescence of in-cell western blot data. Cells were cultured in a 96-well plate and treated with different lipid enzymes inhibitors. This multiplex capacity allows for the assessment of multiple proteins of interest in a single well, which is useful for looking at both total and phosphorylated versions of a protein in a well, or to detect an in-well standard to allow for quantification across a plate (Figure 1).įigure 1 Representative image of an in-cell western blot. In addition, other florescence dyes can be used according to the imaging equipment capacity. Conjugates in the near-infrared (NIR) spectrum are commonly used to reduce auto-fluorescence and noise typically associated with tissue culture plastics. Then, usual techniques of labeling with a specific primary antibody followed by a fluorescent-conjugated secondary antibody are performed. In a simpler manner, cells are grown on a sterile microplate, treated as required and directly fixed and permeabilized in situ. Using the hybrid accuracy of protein quantification of western blotting, and the high-throughput of ELISA, in-cell western blot can be performed directly in 96-well microplates without the need to isolate the proteins from the sample or transfer this protein into any membrane. As a solution, in-cell western blotting was introduced. With only few samples processed at a given time, it became clear that this method can be the bottleneck of any research workflow. With several steps involved, western blotting requires a significant investment in terms of equipment, training and reagents. Separated proteins are then transferred to a suitable membrane that will serve as a carrier for all subsequent immunochemical reactions and imaging. This two-day long technique starts by isolating proteins from samples, which are then separated by size using slab gel electrophoresis. This sensitive immunological method identifies proteins using high affinity antigen-antibody interactions. Western blot is a powerful technique originated in the laboratory of Harry Towbin at the Friedrich Miescher Institute in Basel, Switzerland in 1979.
