With seven microscopes and dozens of scientists in California and Massachusetts, we’ve enabled hundreds of pharmaceutical and biotechnology companies to map complex proteins for structural biology and characterize nanoparticles for manufacturing quality control. John’s arrival positions us well to broaden our service offerings and build an even stronger team for the future.” 

In June 2023, NIS received a growth equity investment from Ampersand Capital Partners to support its worldwide growth initiatives, including expanding microscope capacity and adding complementary services to further serve the needs of existing and future customers.

“As the largest commercial provider of cryo-EM services today, NIS is at the forefront of innovation and new application development for this powerful technique.
