Non-Invasive, Early Detection of Colorectal Cancer Mutations from Tissue Samples.

ColoScape™ Colorectal Cancer Mutation Detection Kit

ColoScape™ is a real-time PCR kit designed for non-invasive, sensitive and early detection of colorectal neoplasia associated DNA markers from FFPE tissue samples. The kit utilizes DiaCarta’s proprietary QClamp® TaqMan-based PCR technology which leverages a sequence-specific clamp made by xeno-nucleic acid (XNA) to suppress PCR amplification of wild-type DNA template and selectively amplify only mutant DNA template. This technology enables a rapid, reproducible and affordable solution which employs a simple workflow and PCR machines that are commonly used in research labs.

Greater than 95% stage I colorectal cancers identified


Robust multiplex TaqMan qPCR assay


Highly sensitive detection utilizing XNA-based clamping technology


Ready to run on most qPCR machines


20 proprietary DNA markers from 4 oncogenes


Less than 3 hours of assay run time
