Abstract (en)

[origin: CA2524265A1] The present invention relates to the detection of somatic cell mutations, particularly as part of a method to screen for cancer or precancer. The disclosure includes techniques for extracting and isolating oligonucleotides from a patient and conducting hybridization assays. Preferred embodiments include a combination of the following steps: extracting a biological sample from a patient, purifying a nucleic acid from a biological sample, amplifyin g a nucleic acid, isolating a nucleic acid in single stranded form, cyclizing a nucleic acid, elongating a nucleic acid, controlling hybridization stringenc y, amplifying a nucleic acid on a chip, and detecting hybridization.
