Universal and Modular Method for Single-Cell Barcoding of Bacteria and Archaea

This technology employs Tn7 transposon machinery to integrate 126-base single-stranded DNA barcodes into bacterial and archaeal genomes at precise loci. Its design features interleaved constant regions with random sequences and includes PCR jackpotting cassettes to ensure amplification fidelity by distinguishing genuine signals from artifacts. Flexible primer binding sites allow for tailoring amplicon lengths to various sequencing platforms, and the use of synthetic short single-stranded DNA cuts costs compared to traditional double-stranded constructs. These modular elements provide robust, high-throughput capabilities suitable for single-cell resolution studies and broader population analyses.

Description

What sets this approach apart is its versatility and cost-effectiveness, achieved through refined barcode design and streamlined integration. The method combines precise genomic targeting with adaptable sequencing compatibility, facilitating accurate detection of cellular dynamics in diverse microbial populations. Its modular construction ensures future enhancements can be integrated without overhauling existing barcode libraries, making it a resilient and future-proof tool. Such differentiation makes it an attractive option for researchers looking to efficiently monitor evolutionary processes and microbial demographics across various environments.
