MAPK, KRAS, BRAF FFPE Reference Standards
The ONCOREF™ series of molecular reference standards is generated using footprint-free genome editing with the CRISPR/Cas9 platform. Because these samples are footprint free – meaning that no selection markers are employed in the engineering process – you are able to focus on the mutations in your samples, rather than having to worry about the presence of residual recombinase sites or genomic footprints from other gene editing technologies, such as rAAV.
Reference Standard Features:
• Most comprehensive MAPK mutation panel on the market
• Footprint-free genome editing
• Isogenically-paired mutant and wild-type cell lines
• Homozygous knock-in of the desired mutation
• Reference cell lines are expanded from single-cells, ensuring maximum homogeneity
• Available in multiple formats, including slides, scrolls, and full FFPE blocks

About the MAPK Pathway
The MAPK signaling pathway encompasses a series of signal transduction events that flow from the engagement of EGFR at the outer cell membrane, through KRAS, BRAF, MEK, and ERK. MAPK signaling ultimately results in transcriptional activation of key genes that promote cellular proliferation, survival, differentiation, motility, and angiogenesis. As such, the MAPK pathway is one of the most frequently activated pathways in cancer, and several drugs have pharmacogenomics profiles that depend upon the MAPK mutational status.

CRISPR/Cas9 is rapidly enabling the development of new tools for enhancing our understanding oncogenic mutations in cancer. In order to aid in advancing cancer diagnosis and treatment, Applied StemCell has recently engineered a series of 40 isogenic cell lines that feature diverse mutations in the MAPK pathway. These mutant lines are available as isogenic pairs for applications in lead compound discovery, or as FFPE and nucleic acid reference materials for assay development. This webinar will focus on ASC’s efforts in developing these research tools, as well as applications of the materials for the advancement of cancer research.
Highlights of this talk:
- Overview of molecular reference materials
- Workflow and QC for ONCOREF™ cell line generation
- Advantages of CRISPR-engineered molecular reference standards
- Applications of reference materials in assay development
- Q & A
How are your cell lines generated? ASC uses CRISPR/Cas9 technology to enable precision genome editing in its MAPK mutation panel series. This technology allows for footprint-free gene modification, meaning that you don’t have to worry about the presence of selection markers or other genomic footprints during the development of your assay technologies.
How do you validate mutational status in your cell lines? All of our MAPK mutation panel cell lines are expanded from single clones. This ensures maximum homogeneity of the genetic profile. After clonal expansion, we confirm the mutational status of the cell line using Sanger sequencing.
Do you offer mixtures of mutant and wild-type DNA? ASC does not currently provide off-the-shelf cell line mixtures, but we can generate custom FFPE blocks to meet your particular research needs through our custom FFPE cell line services.
