Learn More About Platinum®Single-molecule Protein Sequencing at Your Fingertips
NGPS is made accessible with sequencing and library prep kits.
Our end-to-end solution includes everything you need to prepare libraries, sequence proteins, and analyze results. Every lab can quickly and accurately identify proteins with a simple workflow that makes data interpretation and protein insights accessible.
How it Works
NGPS identifies proteins using unique kinetic signatures based on the binding kinetics of amino acid recognition events. Library preparation and sequencing kits contain reagents to digest and functionalize proteins and immobilize peptides on sequencing chips.
Platinum® sequences individual peptides by capturing the florescent signal from each N-terminal amino acid (NAA) binding event. Aminopeptidases cleave each N-terminal amino acid, exposing the next for recognition, and the process repeats until the whole peptide is sequenced.

The Power of Next-Gen Protein Sequencing™
With the power of the Platinum V3 sequencing kit, researchers can look deeper at protein variation
with improved peptide alignments and deeper coverage. Protein identification and inference powered by kinetic signatures is amplified by the addition of aspartic acid (D) recognition, our kinetic database, and AI-powered software model driving confidence for protein identification
Our V3 recognizer set expands access to the amino acid diversity in the human proteome by more than two-fold since published in Science, 2022.
Aspartic acid (D) accounts for nearly 5% of amino acids where the D recognizer — together with improved performance of LIV, NQ, and R recognizers — elevates the ability to explore the human proteome with increased coverage and value to maximize your research.
