Automated capillary Western blot system for sensitive protein detection and quantification with minimal sample use.
The ProteinSimple Jess Western Blot System is an automated capillary-based immunoassay instrument optimized for precise protein detection and quantification, widely used in molecular biology and biotechnology research fields such as *molecular diagnostics* and *synthetic biology*. This system integrates advanced automation to enable high sensitivity and reproducibility while significantly reducing sample and reagent consumption, making it essential for workflows requiring streamlined protein analysis.
Key technical specifications and features include:
The Jess system’s combination of automated immunoassay technology with capillary electrophoresis makes it indispensable for research in cell imaging, molecular cloning workflows, and biomedical engineering. The platform supports various sample types while minimizing operator variability, thus enhancing experimental reliability in biotechnology laboratories and clinical diagnostics settings.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
