Ten years ago, AmplideX® PCR/CE technology revolutionized how CGG repeat expansions in the FMR1 gene could be detected and analyzed, simplifying the testing process and delivering meaningful results within hours, not days.  Today, this same technology has not only extended these same benefits to other repeat expansion targets, including C9orf72, DMPK, and HTT, but also new applications, including the determination of gene copy number.

Introducing the AmplideX PCR/CE SMN1* and AmplideX PCR/CE SMN1/2* Kits, which apply the simplicity and streamlined testing workflows of AmplideX technology to quantify SMN1 and SMN2 copy number in less than 4 hours. Requiring only 50 minutes of hands-on-time, highly scalable to process over 90 samples per run, and compatible with the established suite of Applied Biosystems™ Genetic Analyzers these kits put sensitive and accurate detection of SMN1 and SMN2 copy number within the reach of laboratories everywhere.

 

Features and Benefits

Reduced Complexity
  • Similar workflow for AmplideX PCR/CE FMR1*†and DMPK*† kits eases implementation and training.
  • Scalable design enables high-throughput testing.
  • Automated copy number reporting streamlines data analysis.
Optimized Workflow
  • A simplified workflow with fewer hands on steps and no overnight hybridization.
  • Fully kitted solution with fewer incoming QC steps.
  • DNA-to-data in less than four hours with only 50 minutes of hands-on-time.
Quality Results
  • Differentiates between 0, 1, 2, 3, ≥4 copies for both SMN1 and SMN2 to cover range of expected results.
  • High specificity for both SMN1 and SMN2 ensures reliable results.
  • Accurate copy number resolution demonstrated through comparisons with multiple orthogonal methods.
