Abstract
A heterologous DNA barcoding method is provided. The method includes (a) providing a DNA microarray having DNA oligonucleotide spots, which are distinguished from each other by their barcode sequences, (b) providing a microwell array having microwells whose spatial arrangement corresponds to that of the DNA spots on the DNA microarray, (c) loading a solution of samples containing target nucleic acid sequences into the microwells, (d) assembling the DNA microarray to the microwell array to form micro reaction spaces in which the DNA spots are spatially separated by the microwells, (e) allowing the oligonucleotide sequences of the DNA spots to react with the target nucleic acid sequences of the samples in the micro reaction spaces to combine the sequence information of the DNA spots with the sequence information of the samples, and (f) separating the DNA microarray and the microwell array from each other to obtain reaction products including the barcode sequences.
