9G DNAChip: a platform for the efficient detection of proteins

According to the proposed DAGON method, the CRP and PSA antigens with the concentrations of 1 pg ml(-1) to 10 pg ml(-1) range can be easily differentiated in the buffer matrix. Moreover, it is for the first time that the multiple antigens with the concentrations of 1 pg ml(-1) and 0.1 pg ml(-1) can be detected in the mixture of the proteins without an amplification technique.
