The actual time savings from eZwest come from freeing up the researchers’ time: instead of being tied to their lab timer and western blot, they can focus their efforts on other important tasks.

These times are comparable to those associated with manual processing. To achieve the highest western blot sensitivity, the eZwest Lite requires overnight processing, although assays known to have strong signals can be processed more quickly using a shortened, three-hour protocol. Freeing up time and improving consistency of results The instrument doesn’t take up much space on the lab bench, it operates quietly, and it carries out an automatic cleaning program after each run. The user-friendly interface enables the quick and simple operation and creation of custom protocols that can include as many steps and substeps as needed. “ With eZwest Lite, the cost per blot is the same as with conventional manual processing, and this platform recovers the typically expensive primary antibody, so researchers can use it multiple times.”ĮZwest Lite can process two membranes simultaneously in its cassette using the same reagents and conditions. “The expense of consumables is a key consideration in many research labs,” explains Sherlin Lee, Marketing Specialist at GenScript. Plus, the platform recovers the primary and secondary antibodies for re-use on future blots, saving even more costs.

This instrument performs the membrane blocking, primary and secondary antibody incubations, and all washing steps of the western blot procedure.

US biotech GenScript is helping researchers from labs of all sizes eliminate this bottleneck and free up their time with the eZwest Lite – a cost-effective, automated western blotting platform that is easy to use and provides consistent high-quality results. Affordable automated western blotting in every lab Various automated tools are available on the market to eliminate the need for hands-on processing, but these are often costly and out of reach for many research groups. Nevertheless, the blocking, incubation, and washing steps of the procedure create a significant time bottleneck for researchers. Precast gels, user-friendly electrophoresis and transfer devices, high-quality antibodies, enhanced detection chemicals, and digital imaging systems are all readily available and help streamline the western blot workflow and increase the sensitivity of the assay. Tremendous improvements have become available for the western blot technique over the years. Plus, the high number of steps provides ample opportunities for introducing experimental variation or mistakes. In one survey, 41% of the scientists reported that their western blots fail at least 25% of the time.Ī wide range of factors – involving experimental samples, reagents, and other materials, along with the researcher’s technical implementation of the procedure – influence the western blot’s reliability and reproducibility.
Room for improvementĭespite its frequent use, obtaining quality results from a western blot can still be challenging. It has helped us better understand the proteins involved in the development of multidrug resistance it has enabled researchers to identify antibodies that allowed them to characterize the then-novel retrovirus behind the AIDS epidemic it even aided the discovery of tau proteins, key players in Alzheimer’s disease. Western blotting has also played a central role in countless notable discoveries. It is the most-used protein analysis technique and is routinely performed in biochemistry and molecular and cell biology labs, reaching every corner of research: academia to industry, basic to translational, drug discovery to in vitro diagnostics. Scientists first described the western blot procedure in 1979, and over the next four decades, more than 400,000 research articles mentioned the technique in their title, abstract, or keywords. Western blotting: an old but gold protein analysis technique A new platform makes automated western blot processing accessible to more labs, freeing up researchers’ valuable time, enabling the recovery of valuable antibodies for re-use, and providing consistent results blot after blot.
