The presentation will also be sent to you.
Feel free to share with colleagues. The
resolution of some slides may be suboptimal
due to the webinar software. Those slides will
look fine in the presentation that we send you.

" it might be better to describe CRISPR not as
scissors but as a Swiss army knife, a tool with a
panoply of functionalities that all stem from the
action of a single molecular machine."

Mammoth Diagnostics provides a CRISPR-based
platform for disease detection.
It uses a simple paper-based test in which a liquid
sample (e.g. saliva) is applied and subsequently, a
color change becomes visible. A smartphone app
can be used to upload that data to the cloud, in
which an analysis is delivered in 30 minutes.

Beam Therapeutics develops therapeutics
using a more precise method of CRISPR
called base-editing. By tethering a modified
CRISPR enzyme and an editing enzyme
together, this technology allows editing to
occur without cutting into the DNA at all.
