Horizon Discovery FFPE, Liquid Biopsy OncoSpan Reference Standards

Horizon Discovery has added two new sample formats to its cell-based OncoSpan reference standards for use in the development and validation of workflows for cancer diagnostic assays. The company's OncoSpan range now includes formalin-fixed, paraffin-embedded and cell-free DNA formats for mimicking solid tumors and liquid biopsy samples, respectively, in addition to its genomic DNA format. Its cfDNA format offers more than 380 variants and 152 genes to help standardize liquid biopsy testing.

These cell line-derived reference standards closely mimic patient samples and offer an unlimited and reproducible resource to help ensure consistency during the establishment and validation of diagnostic assays, Horizon said. All three formats are delivered with batch-specific, next-generation sequencing data, orthogonally validated by droplet digital PCR, to allow researchers to further validate their analysis pipeline.
