At Mirus Bio, Innovation Never Ends

The number of applications that rely on delivery of nucleic acids into cells continues to expand and has become more diverse and complex. Replacing genes, re-programming T cells, producing novel biologics, and silencing mRNA translation, are just some of the noteworthy advances that depend on successful transfection.

That’s why we never stop innovating.

One Size Does Not Fit All

Each of these applications is unique and requires a transfection solution that is intentionally designed to deliver nucleic acid into a variety of cell types – consistently and efficiently.

Since our founding in 1995, we’ve been up to the challenge.
