DNA, rewritten as medicine.
DNA is the foundational information layer of biology: directing the production of RNA and proteins to carry out cellular functions. Until now, DNA could not be used as a medicine because of its immunogenicity and inefficient access to the cell’s nucleus. Serif Biomedicines overcame these challenges by reshaping DNA’s form and function so it works with these barriers, not against them.
How Modified DNA works
Transforming DNA from blueprint into therapeutic.
Serif created Modified DNA by altering the structural and chemical form of DNA to minimize innate immunogenicity during delivery into cells. Modified DNA reverts to unmodified DNA once inside the nucleus, enabling transcription into therapeutic RNA and proteins.
Enhanced with mRNA co-factors
Enabling durable therapeutic expression
Serif has developed mRNA co-factors that are delivered with Modified DNA and transiently express proteins that enhance nuclear entry and gene expression.
Modified DNA combines the best features of mRNA and gene therapy while
mitigating their limitations.
Modified DNA medicines are designed to last longer, be given more than once, and be programmed for cell-specific expression. Built on a scalable platform, Modified DNA has the features of an ideal genetic medicine.
The complete capability stack to design, generate, and optimize.
Serif is building the full suite of technical capabilities for optimizing and manufacturing Modified DNA therapeutics, aided by AI. We optimize DNA and mRNA co-factor sequences and LNPs by learning from massive datasets in a design, build, test, learn cycle, and have developed a scalable manufacturing process.
The shape of things to come.
Serif is building a future where DNA becomes the source code for medicines that can be tailored across diseases and scaled for global impact.
Serif’s initial drug discovery programs are focused on rare diseases and immune programming where Modified DNA’s therapeutic properties offer clear advantages for fulfilling meaningful unmet clinical needs.
