5.4 kb plasmid vector for high-level, constitutive mammalian expression with CMV promoter and antibiotic resistance.
Invitrogen pcDNA3.1(+) Mammalian Expression Vector is a 5.4 kb plasmid designed for high-level, constitutive expression of recombinant proteins in mammalian cell lines. It features the human cytomegalovirus (CMV) immediate-early promoter, ensuring robust gene expression across various mammalian systems.
Key features include:
This vector is widely utilised in fields such as molecular biology, biotechnology, and pharmaceutical research. It is commonly employed in university laboratories, biomedical research centres, and pharmaceutical companies for applications including gene function studies, protein production, and vaccine development. Since its introduction, the pcDNA3.1(+) vector has remained a staple in molecular cloning and gene expression studies, reflecting its enduring relevance in scientific research.
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.
