We asked Seer, could we use their nanoparticles… and to our great relief and surprise and happiness… it worked really well! So, we have exactly what we wanted… [and] if it works with GLP-1, it's going to work for a lot of other biological molecules like it… for lots and lots of different small hormones that we need to measure accurately. All of this is maturing right now… to this really quite magical, remarkable time.

We are very excited to leverage Seer technology to enable deep and fast plasma proteome analysis. The ability to profile thousands of proteins in a discovery manner within an hour from plasma is unprecedented. This capability has redefined how we think about leveraging mass spectrometry on myriad clinical and translational projects.
