Paper Abstract
The real-time and quantitative detection assay is important for the gene detection. With the TaqMan probes for the
detection based polymerase chain reaction (PCR), four targets could be checked in a single process in solution assay. A
new method is developed to immobilize the TaqMan probes on a microarray, which could be used to the multi-target
gene fragment quantitative detection with PCR. A new type microarray scanner is designed for the assay. A thermocycler
system was built into the scanner platform. A new type of the vessel sealed with the gene amplification solution which
could perform the thermo-cycling and scanning. To decrease the background intensity a confocal system was used as the
fluorescent intensity detection in the scanner. To calculate the gene quantity, a standard liner graph was draw with the
fluorescent intensity versus the cycles. From the standard liner, the quantity of the original gene fragment could be
calculated in time with the cycles. This scanner offers the great advantage of real-time quantitative detection of DNA
targets in a microarray.
