[摘要]：DNA-microarray technology is a powerful tool to explore the potentials of functional genomics. Almost a decade back, it was not so easy to trace the molecular pathway process in the pathogenesis of diseases. Today DNA-microarray technology allows identifying candidate genes that are implicated in the development and progression of diseases. Because this technology is new, it remains a challenge to perform DNA-microarray experiments in the laboratory. All the technical factors associated with DNA-microarray experiments have a strong impact on the results and therefore, all parts/steps of the protocol, in particular sample preparation (i.e., RNA isolation, RNA preamplification, and cDNA labeling), hybridization, washing, and scanning settings need to be checked and optimized to obtain reliable results from DNA-microarray experiments. |
