About hC Bioscience

hC Bioscience is an innovator and pioneer of protein editing using context agnostic engineered tRNA. Our First in Class approach for protein editing advances beyond genome editing to direct modification of the proteome.

Science & Technology

Transfer RNA (tRNA) is the essential, often overlooked, molecule that provides the critical translation of genetic code into the proteins that are the building blocks of life. We are creating engineered tRNAs with the power to overcome disease-causing issues in the genetic code as proteins are made.

Focus

Team culture

We are building a diverse inclusive team of dedicated professionals.  Together our success will be born out of belief in our purpose, genuine love of what we are doing, and the integrity and excellence of our daily contributions.

“If you are working on something exciting that you really care about, you don’t have to be pushed. The vision pulls you.”
