Clarity™
EGFR L858R Mutation Quantification Kit

The T2573G mutation results in an amino acid substitution at position 858 in human epidermal growth factor receptor (EGFR), from a leucine (L) to an arginine (R). The L858R mutation accounts for the majority of EGFR-mutated non-small cell lung cancer (NSCLC), and it displays higher sensitivity to first line EGFR tyrosine kinase inhibitor therapy as compared to wild type EGFR. Therefore, monitoring L858R mutation status is crucial for the prescription of targeted therapies and prediction of their clinical responses. The Clarity™ EGFR L858R Mutation Quantification Kit provides ready-to-use reagents optimized for sensitive detection and quantification of L858R mutant DNA from human plasma or serum using the Clarity™ digital PCR system.

Product Performance

.

Clarity™ EGFR L858R Mutation Quantification Kit detected as low as 0.1% of L858R mutant DNA in a high background of 15,000 copies of wild-type EGFR. When measured L858R mutant fraction was plotted against the expected mutant fraction, the results showed excellent linearity from 10% down to 0.1% with an R2 value > 0.999.
