    摘要: It is intended to efficiently determine a base sequence specifically appearing in an expression gene. For this, providing that the expression gene consists of exons (301)...(306) and especially that exon (301) is united with exon (302) and exon (302) with exon (303), an aggregate of base sequences (401) (403) being a union of exon base sequences (301)...(305) and a boundary base sequence obtained by uniting together base sequences(404) and (405) and base sequences (406) and (407) respectively existing over boundaries between exon (301) and exon (302) and between exon (302) and exon (303) is formed, and the aggregate is searched. If a base sequence is one specifically appearing in the expression gene, the number of search results is 1 and otherwise, the number is plural.

    摘要: The invention provides amplification-based methods for detecting hypermethylated or hypomethylated nucleic acid in heterogeneous biological samples, e.g., stool. A screening procedure based on the detection of hypermethylation, preferably at multiples genes, provides a means for detecting various diseases, e.g., colorectal cancer. By using chimeric primers that contain a 5' non-specific portion, the specificity and efficiency of the nucleic acid amplification is improved. Methods of the invention are especially useful in detection of rare events in a heterogeneous sample.
