About Us

Our Technology


We use CRISPR to make precision cuts into a cell's genome and then use our patent-pending plasmid system to insert new genes into the cell. This produces a genetically-altered cell line for research use.

Using Proteins to Color Cells


Our first product line is designed to help researchers visualize proteins and organelles inside the cell. By inserting genes that produce bioluminescent and fluorescent proteins, ExpessCells provides insight that enhances researchers' work.

A Better Way to Insert DNA


Our novel technology allows ExpressCells to create custom cell lines in as few as 30 days. We can insert up to three genes in cells that continue to thrive and divide. We plan to launch commercial operations midyear 2019.
