The CLIP-CHIP oligonucleotide microarray: dedicated array for analysis of all protease, nonproteolytic homolog, and inhibitor gene transcripts in human and mouse.
The CLIP-CHIP oligonucleotide microarray allows the analysis of mRNA transcript levels in a tissue sample for all proteases, nonproteolytic homologs, and protease inhibitors of the human and mouse genome. In the protocol presented in this unit, total RNA is extracted from a tissue, and the resulting mRNA is reverse transcribed into cDNA and dsDNA and then amplified in an in vitro transcription reaction. The amplified antisense RNA is labeled with a fluorescent dye and hybridized to the CLIP-CHIP, which contains unique oligonucleotides that are specifically designed for the protease, nonproteolytic homologs, protease inhibitors, and control samples. After hybridization, the fluorescence intensity of each spot is measured, thus identifying mRNA transcripts that are expressed and allowing basic quantification of expressed transcripts.
