A solution containing two tDNAs in one PCR tube was heated at 95 ◦C for 10 min to separate the dsDNA into ssDNA and then cooled rapidly at 4 ◦C.
Serially diluted DNA samples (40L) were mixed with 0.8mg MNP-2pDNA in 200L assay buffer.
The hybridization reaction was maintained at a temperature of 45 ◦C for 1 h in an incubator.
After hybridization, the MNP-2pDNA/tDNA was washed twice with the assay buffer, then resuspended in 200L assay buffer.
