Vertical slab electrophoresis system for SDS-PAGE, native PAGE, and 2-D electrophoresis with cooling and multi-gel capacity.
The Bio-Rad PROTEAN® II xi Cell is a versatile vertical slab electrophoresis system designed for the separation and analysis of proteins and nucleic acids. This instrument accommodates various electrophoretic techniques, including SDS-PAGE, native PAGE, and two-dimensional (2-D) electrophoresis, making it indispensable in proteomics and molecular biology research.
The PROTEAN II xi Cell is widely utilised in fields such as proteomics, molecular biology, and biotechnology. It is commonly found in university laboratories, biomedical research centres, and biopharmaceutical companies, where precise protein separation is critical for applications like protein profiling, biomarker discovery, and quality control in biomanufacturing.
Introduced in the early 2000s, the PROTEAN II xi Cell remains relevant in modern laboratories due to its reliability and adaptability to various electrophoretic applications.
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.
