VariantFlex™ Custom Platform

Next-generation sequencing (NGS) has revolutionized the genomics field and how IVD developers, laboratories, and clinicians are diagnosing, treating, and monitoring disease and genetic conditions.  With NGS-based assays displacing older methodologies worldwide, it is extremely important that they are proven to be robust, accurate, consistent, and cost-effective in delivering timely results to improve patient care.

As NGS panels grow to include an ever increasing number of important biomarkers, so too must the reference materials used for development, validation, and routine QC. But sourcing sufficient quantities of remnant patient specimens or cell lines bearing all of the necessary variants is expensive, time consuming, and can leave you short of rare or challenging mutations.

With SeraCare’s VariantFlex platform, you can easily get the variants you need at your desired allele frequencies in the format that fits your assay. Your custom reference material will arrive in weeks, thanks to our streamlined process and flexible biosynthetic technology.

Easily build custom reference materials

  • Easily select variants from a library or made to order, and configure to your specific assay
  • Over 180 clinically relevant variants across 45 genes in our constantly growing library
  • Range of variant types – SNVs, Indels, RNA gene fusions, CNVs, Trisomies
  • Patient-like profile, complexity, and sequencing performance attributes
  • Scale easily from development to validation and post-launch run monitoring
  • Targets precisely quantitated with digital PCR
  • Manufactured in GMP-compliant and ISO 13485-certified facilities


Featured Projects
