This preprint just came out. @wchnicholas.bsky.social and team reconstructed and tested the NJ Spike and found that it has the tightest ACE2 binding of any SC2 Spike ever measured. 2/ www.medrxiv.org/content/10.1...

This is wild. Remember the NJ crytic lineage? I posted 18 months ago that the Spike was too divergent to predict ACE2 binding, and asked if someone else could figure it out. Some colleagues took me up on it. Guess what they found? 1/

I'm thrilled to share that the oPool⁺ display is on the cover of this week's #ScienceTranslationalMedicine! We hope that the future use of this platform can accelerate antibody characterization, benefit therapeutic & vaccine development, and facilitate iterative refinements of antibody AI models.
