Branca Bunús Ltd is a pioneering start-up, committed to developing and commercializing cutting-edge gene delivery technology and polymer-based nonviral gene therapies platform technology. Our mission is to transform innovative scientific discoveries into life-changing clinical treatments and become leaders in gene delivery technology and non-viral gene therapy solutions.

Over time, Branca Bunús Ltd has evolved into a leading biotechnology company, specializing in the development and commercialization of high-efficiency transfection reagents, driven by our proprietary "HPAE" technology for both research and industrial applications. We aim to provide cutting-edge solutions that enhance the production of recombinant proteins and viral vectors, making transfection more accessible, cost-effective, and advantageous over traditional methods like PEI or lipid-based reagents.

Our strength at Branca Bunús lies in our talented and highly skilled team, comprising experts in biotechnology, medical science, regenerative medicine, materials and polymer chemistry, alongside seasoned entrepreneurs. We are dedicated to translating advanced scientific research into practical applications that benefit both the scientific and industrial communities.

At the heart of our innovation is a multifunctional cationic polymer, engineered for the efficient delivery of nucleic acids into cells. This polymer is optimized for outstanding transfection performance, providing high yields, excellent biocompatibility, minimal reagent use, cost efficiency, and stability—ideal for large-scale applications.

While we continue advancing gene therapies for rare diseases, Branca Bunús Ltd is also focused on marketing and distributing advanced polymer solutions to meet the evolving demands of the scientific research community. Our flagship product, BrPERfect®, is a cutting-edge transfection reagent that consistently delivers superior results in transient protein and viral vector production. BrPERfect® outperforms competitor products across a wide range of challenging and commonly used cell types, with minimal cytotoxicity. Its exceptional efficiency is due to superior DNA binding, effective cellular uptake, endosomal escape, and high biodegradability.
