| Research Abstract |
The "Cancer cDNA Bank" of colorectal cancer patients was constructed with our unique mRNA assay system.
Total nucleic acids extracted from colorectal cancers were applied to 96-well plates, where poly-d (T) sequences of oligonucleotides were immobilized. After hybridization, the ds-cDNA was synthesized on the plate using the captured mRNA as a template. The resultant sense cDNA removed from the plate was used for RT-PCR for analysis of various genes. The sense strand of the cDNA was repeatedly synthesized using the immobilized antisense cDNA as a template even after storage.
Furthermore, the results of RT-PCR can be easily compared among different specimens, if the same amount of total mRNA was applied to the plate for the ds-cDNA synthesis.
These demonstrated that the "Cancer cDNA Bank" constructed from clinical materials provides almost unlimited supplies of cDNA for multiple gene analysis.
