How it Works

Protein barcoding provides users with a robust method to screen multiple protein variants in a single pooled reaction. Individual proteins are tagged with short, unique peptide barcodes that identify each variant. With the barcoding kit, screened proteins are prepared and barcodes are released for sequencing on Platinum®.

Prepare peptide barcodes for single-molecule sequencing

Sequence peptide barcodes with single-molecule precision

Analyze multiplexed barcodes with relative quantitation

Barcoding Prep Kit

Barcoding Kit

Provides methods for expression of unique peptide barcodes in proteins of interest for downstream sequencing and analysis on Platinum.

The Barcoding Kit contains reagents to prepare and immobilize barcode-tagged peptides for sequencing. Eight unique peptide barcodes are carefully designed for optimal sequencing performance with the Sequencing Kit.

Protein Sequencing Kit
