BRANFORD, Conn. / Apr 30, 2024 / Business Wire / Quantum-Si Incorporated (Nasdaq: QSI) (“Quantum-Si,” “QSI” or the “Company”), The Protein Sequencing Company™, today announced upgrades to its Platinum^® Analysis Software to reduce processing time and increase output and precision of Next-Generation Protein Sequencing™ (NGPS) data from the Platinum^® instrument.

“A core component of our Platinum Analysis Software is a database of predicted kinetic signatures that today, contains nearly two million parameters and is generated by our proprietary kinetic model,” said John Vieceli, Senior Vice President of Product Development at Quantum-Si. “Leveraging artificial intelligence and generated sequencing data, we are able to continuously train our model and improve the accuracy of the database, resulting in higher data output and precision.”

Innovations in this release of the Platinum Analysis Software will provide customers with an average of:

• 55% increase in the number of peptide alignments of protein samples
• 9% increase in the precision of identifying unknown proteins present in a given sample
• 70% reduction in primary analysis time from 85 minutes to 25 minutes

“Innovations to our Platinum Analysis Software represent a significant opportunity to unlock even deeper insights from our Next-Generation Protein Sequencing technology further building upon the improvements we continue to deliver to the sequencing chemistry,” said Jeff Hawkins, President and CEO of Quantum-Si. “The Platinum Analysis Software enhancements we are launching today represent another significant leap forward in our commitment to continuously provide customers with innovations that deliver tangible value to their proteomics research.”
