Widest range of power settings and transfer times Comparison of Western Blotting Transfer Systems Filter papers and membranes are pre-wet and packaged in single-use packages, simplifying assembly of the transfer stack. Transfer conditions must be optimized for proteins of different molecular weights, e.g., to prevent under-transfer (incomplete transfer of proteins out of the gel) or over-transfer (loss of proteins passing completely through the membrane).Ī recent development, these systems utilize specialized apparatus that use proprietary filter papers and specialized buffers to rapidly and efficiently transfer proteins. Both the voltage and the distance between the electrodes then play a major role in governing the rate of elution of the proteins from the gel. The electric field strength (measured in V/cm) that is generated between the electrodes is the driving force for transfer. Voltage is applied between the electrodes and proteins migrate to the membrane following the current that is generated by the applied voltage across the electrodes. During this process, the membrane and gel are placed together, with filter paper between two electrodes. The most common method of transfer in western blotting is electrophoretic transfer, where an electric field is used to elute proteins from gels and transfer them to membranes. Quantitative results such as molecular weight, signal intensity (area), % area, and signal-to-noise for each immunodetected protein are presented in the results table automatically.Gel and Membrane Setup for Electrophoretic Transfer If you're more familiar with capillary electrophoresis, you can see your results in a more traditional electropherogram view too. Simple Western data are displayed by lane in a virtual blot-like image similar to traditional Western blot results. What does the data look like? At the end of the run, Simple Western data are processed automatically in Compass for Simple Western. Blot imaging: Still doing traditional Westerns? You can image chemiluminescence Western blot with Jess's built-in blot imaging system.And with Superplex you can assay in chemiluminescence and 2-color fluorescence on top of Protein Normalization. You can effectively normalize expression of your target protein to get accurate and consistent data, giving you confidence in your results. Jess's proprietary fluorescent reagent measures proteins immobilized in the same capillary as your immunoassay. Protein Normalization: Jess gives you an easy way to see if your samples contain a consistent protein load-just load the Protein Normalization reagent into the assay plate and Jess will take care of the rest.RePlex™: Why bother stripping and reprobing? RePlex lets you run two immunoassays within the same capillary to get all your rich protein characterization data from just one sample!.Take multiplexing even further with Superplex to assay in chemiluminescence and 2-color fluorescence with Protein Normalization at the same time. The Stellar™ NIR/IR Modules bring industry-leading fluorescence detection sensitivity for Western workflows. Multiplex detection: Maximize your time and sample, and get the information you need in one shot by multiplexing in chemiluminescence and infrared (IR) and near-infrared (NIR) fluorescence channels.Jess gives you four different ways to analyze proteins: In just 3 hours you'll have quantitative, size-based data ready for analysis. With proteins now immobilized and the matrix cleared of the capillary, Jess starts the immunoprobing process. Once the separation is complete, UV light immobilizes the proteins to the capillary wall. Voltage is applied to enable separation by molecular weight. Next, your sample is loaded, and capillaries are lowered to make contact with running buffer. Jess begins by aspirating the separation matrix and then the stacking matrix into each capillary. Your sample, separation matrix, stacking matrix, antibodies, and reagents are loaded automatically from a specially designed plate. Best of all, the transition is simple-the same antibodies you use for Western blotting protocols can be used with Simple Western assays.

The variability in the manual processes that impact reproducibility, quantitation, time to result, and overall data reliability is eliminated. All assay steps from protein separation, immunoprobing, detection, and analysis are fully automated. Simple Western assays are automated, capillary-based immunoassays that solve many of the challenges that come with traditional Westerns.
