Capture Efficiency Of Long-Adapter Single-Strand Oligonucleotide Probe Libraries

ABSTRACT

High throughput techniques that can massively produce in parallel, longer DNA sequences of interest can accelerate the decoding of gene functions. LASSO probes are a molecular biology tool that can enrich for DNA targets in a genomic sample via a multiplexed, single-pot reaction for downstream sequencing and/or cloning. Here we have explored aspects of process development and the design of the probes that relate to binding thermodynamics to determine impact on cloned library sequences. Control of ligase concentration, polymerase type, and melting temperature of probe are critical when translating the use of LASSO probes for homogeneous and high fidelity DNA capture.
