Conceptually similar to DNA barcodes, protein barcodes represent a wealth of opportunity for precision proteomics. DNA barcodes have been front and center to major advances in molecular biology research in recent decades with numerous applications. They are used heavily in next-generation sequencing for sample identification in multiplexed libraries, improved resolution in transcriptomics, and genotype enrichment for protein engineering.
Protein barcodes similarly facilitate cutting-edge opportunities with expanding applications. They allow for the precise tracking and identification of proteins in complex samples, with potential applications in drug screening, detecting biomarkers, and tracking protein interactions and functions, Also like DNA barcoding, their full potential is realized with accessible next-generation sequencing technology that enables direct sequencing and identification with single-molecule resolution.
