What's new at Protean?

Arctic-TEV protease His6

We offer cold-adapted form of Arctic-TEV protease with higher activity and thermal stability. This in house developed enzyme shows a superior activity/costs ratio at 6°C. Fully GMP compliant product.

RT-LAMP Diagnostics

Protean Ltd. has developed a new technology for a simple and highly specific detection of various pathogens based on isothermal amplification. The technology is aimed on field and POC test development. The results are readable by naked eye and are processed by a mobile device. A patent application is pending.

ProRT Reverse Transcriptase

ProRT is genetically optimized thermostable enzyme ideal for cDNA synthesis and one-step amplification techniques, such as RT-LAMP and RT-qPCR.

Taq DNA Ligase

Thermostable DNA Ligase for advanced techniques such as, Gibson assembly, Ligase chain reaction (LCR), NGS, inverted repeat amplification and gene synthesis from Thermus aquaticus.

Bst DNA Polymerase LF

Bst DNA Polymerase, exonuclease minus, exhibits a strong strand displacement activity making it an ideal candidate for isothermal amplification (LAMP), whole genome amplification (WGA), and multiple displacement amplification (MDA).

Free Samples Available!

We offer free samples of any recombinant protein or enzyme for testing purposes including free shipping (EU only). Please feel free to contact us by email or order specific enzyme from the catalog through our ordering system. Limited-time offer!

A nonspecific nuclease from S. marcescens

We offer highly active nonspecific endonuclease from Serratia marcescens for DNA and RNA removal and viscosity reduction of cell lysates.

S. aureus Endolysin

In collaboration with our academic partner we launch the production of Endolysin 812, a highly active killer enzyme of the major pathogen S. aureus including MRSA strain. It selectively kills only S. aureus cells leaving other commensal bacteria intact.

Novel anti-AHP antibodies

We introduce a unique set of monoclonal antibodies against Arabidopsis thaliana phosphotransfer proteins 2-5. These antibodies represent an excellent tool for mapping of multistep phosphorelay signaling in A. thaliana.

New website!

We are pleased to welcome you on our brand new website! We have revamped the look and upgraded our information portal to an e-shop where you can easily purchase recombinant proteins online. Feel free to explore everything we have to offer!
