Highly specific monoclonal antibody for detecting and purifying FLAG-tagged fusion proteins in diverse assays.
The Monoclonal ANTI-FLAG® M2 Antibody (F1804) is a highly specific and sensitive tool designed for the detection and purification of FLAG-tagged fusion proteins. This antibody binds to the FLAG peptide sequence (DYKDDDDK) present at the N-terminus, Met-N-terminus, C-terminus, or internal sites of fusion proteins, facilitating their identification and isolation across various expression systems.
This antibody is widely utilised in molecular biology, biotechnology, and biomedical research for applications such as protein expression analysis, protein-protein interaction studies, and protein purification. It is commonly employed in university laboratories, biomedical research centres, and biotechnology companies. The F1804 antibody has been a staple in research since its introduction and continues to be relevant in current scientific investigations.
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.
