The LeXPrep RNA & DNA Library DualPrep Module is a high-performance solution engineered for the synchronous preparation of both RNA and DNA libraries from a single sample. Specifically optimized for pathogenic microbial samples, this integrated module eliminates the need for separate workflows, providing a comprehensive genomic and transcriptomic snapshot of complex mixed populations.
The DualPrep Module consolidates multiple complex steps into a streamlined, single-tube process, including:
This module is designed for universal compatibility and performs seamlessly with the LeXPrep Universal Stubby Adapter (UDI) Module and LeXPrep Universal Adapter (MDI) Module for MGI, ensuring a flexible path to results on any major sequencing platform.
Flexible Multi-Analyte Compatibility
Rapid Single-Tube Operation
Unmatched Efficiency and Uniformity
Advanced Pathogen Contamination Control

If you are using co-extracted total nucleic acids, ensure you quantify RNA and DNA separately using high-sensitivity methods (e.g., Qubit) and follow the recommended PCR cycles for your specific input. Additionally:
This is often caused by residual EDTA or an incorrect pH level inhibiting enzymatic digestion. We recommend purifying your starting material with 2X LeXPrep SP Beads and replacing the elution buffer with Nuclease-Free Water to ensure optimal enzyme activity.
Yes. This module can tolerate samples containing up to 6 μL of 1 mM EDTA (resulting in a final concentration of 0.3 mM in the 1st strand synthesis). If your sample solvent exceeds this threshold, a bead-based cleanup is necessary before proceeding.
Yes. When co-preparing libraries from mixed samples, a higher DNA-to-RNA ratio may result in slightly larger fragment lengths during enzymatic digestion. You can easily compensate for this by adjusting the fragmentation time according to the insert lengths recommended in the manual.
Absolutely. Libraries prepared with this module are fully compatible with the LeXso Hybrid Capture Reagents. This integration significantly shortens the turnaround time for pathogen-targeted sequencing and simplifies the experimental burden.
The LeXPrep DualPrep Module is engineered to match the performance of our specialized DNA kits. Benchmarking against the LeXPrep EZ DNA Library Preparation Module v2 shows nearly identical library yields, mappability, and capture performance, ensuring you don’t sacrifice DNA data quality when choosing a dual-analyte workflow.
