Horizon FFPE standards eliminate the variability associated with patient-derived reference standards, and avoid the hassle of sourcing, characterizing, and documenting your own cell line mixes. The standard is provided at an allelic frequency of 0% for variants of the indicated gene and may be used to dilute corresponding variant standard to generate lower allelic frequencies for limit of detection studies and validation of your pre-analytical phase of the workflow. Horizon’s Base-Seq products are all derived from human cell lines. Using a proprietary method of mild fixation and homogenous paraffin embedding, we generate highly-reproducible and consistent FFPE curls. With any commercially available FFPE extraction protocol, our standards yield high molecular weight DNA. This format ensures that they may applied to a wide-range of assays including qPCR, Sanger sequencing, next-generation sequencing, mass array, and more.

With this product you are able to:

• Evaluate of workflow integrity from pre-analytical DNA extraction to post-analytical bioinformatics
• Analyze the sensitivity of your workflow
• Optimize and validate new cancer panels and routinely monitor the performance of your assay
