Initial Machine Testing
When we unplugged the mounting plate from the open PCR circuit board, the display screen on the PCR box did not work.
When we unplugged the white wire that connects the open PCR circuit board to the heating block, there was no temperature reading on the display screen.
(First Open PCR test: 10/25/12. We had a successful and simple run of PCR)

Research and Development
Specific Cancer Marker Detection - The Underlying Technology
The r17879961 cancer-associated sequence (AAACTCTTACACTGCATACA) will produce a DNA signal because of its nucleotide variation (ACATTGC to ACACTGC). This T-C change results in an isoleucene to threonine substitution. In a study in Finland, patients with colorectal cancer (CRC), the most common cancer associated with the DNA sequence change, had the allele 7.8% of the time while patients without CRC had the allele in 5.3% of patients, showing a significantly higher association in CRC patients. PCR detection will only give a signal if this allele is present.
