The pro-siRNA technology platform

Xiaomo possesses a revolutionary RNAi technology, called the pro-siRNA (for ‘prokaryotic siRNA’) technology, which is invented by Prof. Linfeng Huang (City University of Hong Kong), founder of Xiaomo, and Prof. Judy Lieberman (Harvard Medical School, USA) and published in top biotech journals.

The pro-siRNA technology employs bacterial cells as the ‘factory’ of siRNA and is the world’s only bioengineering method for siRNA production. Comparing to other methods, this technology offers the lowest production cost and large-scale production capacity through an environmentally friendly production process. In addition, the pro-siRNA technology offers the best-in-class high-throughput RNAi screen method.
