Seraseq® Custom Solutions for NGS


Expert-designed custom reference materials supporting the entire NGS assay lifecycle

Complementing our industry-leading portfolio of ready-to-use reference materials for NGS-based assays, SeraCare develops custom, highly-multiplexed solutions tailored to your workflow and unique specifications. We tap into our comprehensive scientific knowledge and experience to quickly build NGS reference standards carrying clinically-actionable genomic variants or genomic signatures, for solid tumor and hematological malignancy profiling, liquid biopsy, and reproductive health.

Flexible. Scalable. Bespoke.

NGS Lab Pipette

SeraCare’s custom reference materials are carefully engineered with a wide range of variants, including SNVs, indels, DNA translocations, RNA fusions, and CNVs, in any combination you need and at virtually any allelic frequency. We can also build custom versions of complex genomic signatures such as TMB and MSI for assays predicting responses to cancer therapies. Formats include purified gDNA, RNA, and cfDNA, for immediate input into NGS assays, as well as patient-like FFPE and synthetic plasma, for accurately emulating extraction from clinical samples.

Custom reference materials give you unparalleled flexibility and scalability for validating your NGS workflow. Our biosynthetic spike-in technology and efficient, quality-controlled manufacturing let us provide a rapid turnaround time for your custom materials – typically 8-12 weeks.


  • Select from hundreds of clinically actionable variants across dozens of genes or specify a custom sequence
  • Opt for different well-characterized genomic backgrounds or request a custom background
  • Scale easily from development to validation and post-launch run monitoring
  • VAFs and copy numbers precisely quantitated with digital PCR, or verified by NGS
  • Manufactured in ISO 13485-certified GMP-compliant, US FDA audited facilities for traceability from sourcing through processing and delivery

Featured Projects


  • Comprehensive genomic assay development: Custom cancer panel with over 60 variants at 10% allele frequency to support a platform and system for targeted cancer applications
  • Liquid biopsy validation: Custom ctDNA panel with key therapeutic variants (such as EGFR pT790M) as low as 0.1% to help stratify patients for targeted drug therapy
  • Tumor profiling routine QC: Custom version of off-the-shelf tumor DNA reference materials to monitor daily run performance of a tumor profiling assay
  • NIPT assay development: Customized trisomy 21, 18, 13, and euploid materials across a range of fetal fractions to support a ground-breaking new platform and consumable launch
