SPRISelect Size Selection Performance and Data

SPRISelect Size Selection Solution Performance & Data

Next Generation Sequencing (NGS) is the most pervasive technology in genomics research today. The long list of front-end applications has varied library preparation requirements that demand flexible solutions. The size of DNA has a direct impact on generating desired sequencing results. The SPRISelect Reagent Kit is designed to give scientists more flexibility and control over the size selection process. With proven, industry leading Solid Phase Reversible Immobilization (SPRI) technology, this reagent provides robust, reproducible and customizable size selection.

  • Tunable from 150 to 800 base pairs allows for easy adjustments for specific applications and sequencers
  • Efficient mag bead technology eliminates the need for gels, chips or special instrumentation
  • Scalable from manual to automated for high throughput processing in 96-well plates


Dual Size Selection Capability

SPRISelect was used for dual size selection on sheared gDNA from E. coli.

Reproducible & Tunable

SPRISelect is manufactured to tight specifications ensuring run to run and lot to lot reproducibility.

Two different size selections were performed on sheared gDNA from E. coli using SPRISelect. Triplicates were performed per size selection. Each of the triplicates show very consistent size selection capabilities.

Less Hands-On Time Than Other Suppliers

SPRISelect and two other commercially available kits were used for size selection on sheared gDNA from E. coli. The left most bar for each kit represents the time for single size selection. The SPRISelect workflow for a single size selection is 4.2 and 2 times faster than supplier A and supplier B, respectively. The right most bar for each kit represents the time for dual size selection. The SPRISelect workflow for dual size selection is 3.8 and 2 times faster than supplier A and supplier B, respectively. SPRISelect has the lowest processing time out of all three supplier by at least 50%. The times were based on performing size selection for 8 samples.

Simple to Run Manually or Automated

Estimated hands-on time and total time in minutes, required to perform dual size selection on 8, 24, 48 and 96 DNA samples using SPRISelect. The different methods can be performed either manually or automated on a Biomek workstation. The table represents automation times performed on a Biomek i7 hybrid. Difference in time between manual and automation is indicated. NR=Not Recommended.
