From: Array-based techniques for fingerprinting medicinal herbs
Method of manufacturing and using oligonucleotide or gene-probe based microarray for fingerprinting herbal plants. The species-specific gene or oligonucleotide probes can either be PCR amplified or chemically synthesized for microarray printing. Fingerprinting herbal species with a single dye system is shown in the figure; however, it is possible to use a dual-dye system where one sample can be a reference and other a test sample, or both samples can be test samples.
