| Outline of Final Research Achievements |
In general, the length of poly (A) in eukaryotic mRNA shows a wide distribution, and at present, there is no precise and simple method to determine it. A novel method for its determination was developed with the improvement of conventional anchored RT-PCR, and designated as PACHINCO (Poly (A) Capture by Hairpin Chimeric Oligonucleotide)-RT-PCR. The new method can be applied for the comprehensive determination of poly (A) in whole cellular mRNAs with simply replacing 5' primers used for PACHINCO-RT-PR with sequences involved in the corresponding 3'UTRs of mRNA. Indeed, the method was optimized for an automatic microchip DNA electrophoresis apparatus, and the elongation of poly (A) of Per1 mRNA was identified using this system.
