Detection and Quantitation of Protein with ScanLater Western Blot Detection System
20 Nov 2014This application note reports on a novel system for Western Blot membrane protein analysis that is incorporated into SpectraMax® i3 and Paradigm® Multi-Mode Microplate Readers. An extended dynamic range due to reduced background is demonstrated, as well as stability of detection over time and number of reads. In addition, a comparison of Scanlater™ Western Blot System to a chemiluminescence method demonstrates improved sensitivity.

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.

Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Gel Doc / Image AnalysisGel documentation (gel doc) or gel imaging systems are used for the analysis of proteins, antibodies and nucleic acid immobilized in polyacrylamide or agarose gels, membranes or microarrays. Explore a range of a gel imaging systems, densitometers, scanners, transilluminators or UV lamp + CCD cameras for your image analysis solutions. Colorimetric, fluorescent and/or radioisotopic samples can be visualized and documented for further analysis. See gel doc / Image analysis software for quantitative 1D and 2D analysis of your samples.

Proteins of interest can be easily labeled and detected on light-based detection instruments. Immunoassay kits allow you to identify a specific protein of interest and protein detection beads or antibody microarrays allow you to identify multiple specific proteins at once. Protein interactions and enzyme activity can also be monitored with protein-protein interaction assays. Additionally, the biophysical characterization of proteins is made easy with biokinetic analyzers.
