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.

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.

Essential in molecular biology, this technique helps visualize results for accurate quantification and documentation. Discover top imaging systems and compare user-reviewed options in our directory.Assay DevelopmentThe process of proving an assay to be sensitive with respect to the target is known as assay development. The assay should be able to characterize novel compounds and measure the potency of these compounds against a validated biological target.MultiplexingMultiplexing refers to the ability to measure multiple targets or analytes simultaneously in a single experiment. This technique is valuable for high-throughput screening, diagnostics, and complex assays, as it increases efficiency and data quality.
