A modified restriction display PCR method in sample-labelling of DNA microarray.
The restriction display PCR is a useful technique for studying the diversity of gene expression. This method involves ligating the digested genes with adapters and amplifying the gene fragments by PCR using universal and selective primers. In this study, we improved this restriction display PCR method by using Cy3-UP, a fluorescently labelled universal primer, in place of Cy3-dCTP in sample-labelling for DNA microarray. The results show that this new method increases significantly the sensitivity of the assay, and will have a wide application in the DNA microarray field.
