Mimix™ OncoMatch™ Lung Cancer Negative, FFPE Reference Standard

Size:1 section

The Mimix™ OncoMatch™ Lung Cancer Negative FFPE Reference Standard (TMB score 19) serves as a matched normal control for paired tumor-normal analysis. It can be used alongside the Lung Cancer Positive FFPE Reference Standard (TMB score 48) to support identification of somatic variants using molecular biology assays such as qPCR, ddPCR, Sanger sequencing and NGS.

Molecular diagnosis of lung cancer often requires precise differentiation between somatic and germline variants. The Mimix OncoMatch lung cancer negative FFPE reference standard provides a matched normal control derived from the same individual as our lung cancer positive reference material (HD851, available separately). When used together, they support laboratories to confidently verify pipelines and identify true cancer-associated variants by filtering out germline polymorphisms that could otherwise lead to false positives in tumor-only testing approaches. The Mimix OncoMatch lung cancer negative FFPE control comes with Tumor Mutational Burden (TMB) score, a biomarker widely used to predict an individual’s response to immune checkpoint inhibitors.

Our Mimix reference standards are produced under ISO 13485 and undergo rigorous QC testing, leveraging over 14 years of experience in reference material development. Each batch is thoroughly characterized using whole exome sequencing to confirm the absence of lung cancer specific variants while maintaining the appropriate germline background. This means you can trust the quality of our controls for greater confidence in your results. 

If you need a FFPE reference standard with your preferred blend of tumor and matched normal lung cell lines, we can provide a made-to-order control. You can define the desired tumor-to-normal ratio or your desired TMB score, and we’ll create customized FFPE reference material derived from lung tumor and matched normal cell lines that meet your requirements. Enquire now using our made-to-order options.

Key features:

• Representative matched lung tumor and normal samples from the same genetic background
• Unedited, single source reference standard for patient-like performance
• Prepared in FFPE format to mimic patient samples, for end-to-end workflow verification
• Enables paired tumor-normal analysis when used with the matched lung cancer positive reference standard (HD851)
• Well-suited for creating custom dilution series with the positive reference standard to precisely challenge and establish LOD for molecular assays
• Batch-specific WES data for verification of NGS workflows, confirming the germline profile
• TMB score
• Made-to-order options available for preferred tumor-to-normal blends
• ISO 13485 manufacturing: Produced under stringent quality management systems with extensive documentation and lot-specific quality control metrics

Batch-specific NGS data

The Mimix OncoMatch lung cancer negative FFPE reference standard comes with batch-specific NGS data. You can access the VCF file here. Each batch was sequenced using Agilent's CREV4 (Clinical Research Exome) kit at a depth of 250x on Illumina platform and run through the Illumina DRAGEN Germline Pipeline for mapping, sorting, and variant calling.
