High-copy plasmid vector for direct cloning of Taq-amplified PCR products with dual antibiotic selection.
The Invitrogen pCR2.1-TOPO vector is a high-copy number plasmid designed for rapid and efficient cloning of PCR products, particularly those amplified using Taq DNA polymerase. This vector facilitates the direct insertion of PCR products into a plasmid without the need for post-PCR modifications, streamlining the cloning process.
This vector is widely utilised in molecular biology and biotechnology research for applications such as gene cloning, sequencing, and in vitro transcription. It is commonly employed in university laboratories, biomedical research centres, and biotechnology companies. Since its introduction, the pCR2.1-TOPO vector has remained a valuable tool in molecular cloning workflows.
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.
