LanteRNA

LanteRNA, also known as Stealth Labels Biotech AB, is a deeptech company based in Gothenburg, Sweden, that specializes in advanced fluorescence-based tools for mRNA research and therapy development. The company has developed proprietary fluorescent base analogues, such as tCOTP, which can be integrated directly into mRNA sequences during synthesis. Unlike traditional fluorescent dyes that attach externally and can disrupt RNA structure or function, LanteRNA’s stealth labeling technology allows for minimal impact on the molecule's natural behavior. This enables researchers to accurately track mRNA in real-time, facilitating studies on intracellular uptake, protein translation, and overall mRNA performance without compromising the integrity of the genetic message.

This technology is designed to address critical needs in the pharmaceutical and academic sectors, particularly for those developing next-generation nucleotide drugs and mRNA vaccines. By providing a clearer, non-perturbing method to visualize mRNA behavior, LanteRNA helps partners gain deeper insights into drug delivery processes and therapeutic efficacy. The company’s solutions support high-throughput applications and have been validated through collaborations with leading research institutions and industry partners. Founded in 2021 based on research from Chalmers University of Technology and AstraZeneca, LanteRNA continues to evolve its platform to support the advancement of RNA-based medicines against various diseases.
