    Abstract: Methods and kits directed to processing a fresh fecal sample from a human subject by a process comprising removing a portion of a collected fecal sample and adding the removed portion of the sample to a buffer that prevents denaturation or degradation of blood proteins, and stabilizing the remaining portion of the fecal sample with a stabilizing buffer that maintains nucleic acid integrity.

    Abstract: A method for detecting a methylated genomic locus is provided. In certain embodiments, the method comprises: a) treating a nucleic acid sample that contains both unmethylated and methylated copies of a genomic locus with an agent that modifies cytosine to uracil to produce a treated nucleic acid; b) amplifying a product from the treated nucleic acid using a first primer and a second primer, wherein the first primer hybridizes to a site in the locus that contain methylcytosines and the amplifying preferentially amplifies the methylated copies of the genomic locus, to produce an amplified sample; and c) detecting the presence of amplified methylated copies of the genomic locus in the amplified sample using a flap assay that employs an invasive oligonucleotide having a 3′ terminal G or C nucleotide that corresponds to a site of methylation in the genomic locus.
