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

Abstract

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. © 2011 The Royal Society of Chemistry.
