Increasing Western Blotting Assay Efficiency with Four-Color Detection
3 Apr 2019Until now, western blot multiplexing technology has enabled simultaneous detection of up to two spectrally-shifted fluorophores on a single blot. This application note describes how the Azure Biosystems Sapphire Biomolecular Imager can effectively detect and quantify four fluorophores for even greater assay efficiency.

Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms. Find the best cell-based assay products, kits and equipment with our peer reviewed product directory: compare products, check customer reviews and receiving pricing direct from manufacturers.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Western BlottingWestern blotting equipment is used to transfer and identify specific proteins within a sample, reveal protein modifications, as well as give a semi-quantitative estimation of their concentration. Western blotting equipment includes all apparatus necessary to transfer proteins from gel to membrane and subsequent processing steps. Protein transfer can be performed by electroblotting with wet, semi-dry and dry transfer systems onto nitrocellulose and PVDF membranes. Blocking, washing and labeling of membranes follows, involving buffers, blocking reagents, blotting / incubation trays, labeling reagents, immunoblotting assays, antibodies and conjugates. Automated equipment for these steps is available to accelerate your lab workflow. Finally, detection and imaging of proteins can be conducted using gel documentation and imaging systems.
