TUMOR MARKER, METHYLATION DETECTION REAGENT, KIT AND APPLICATION THEREOF

摘要

Disclosed in the present invention are a tumor marker, a methylation detection reagent, a kit and an application thereof. A colorectal cancer specimen may be distinguished from a normal human fecal specimen by means of detecting the methylation level of a TLX2 gene promoter region or jointly detecting the methylation levels of COL4A2 and TLX2 gene promoter regions. The present invention utilizes a methylation detection reagent containing a TLX2 gene or the two genes of COL4A2 and TLX2 to detect colorectal cancer.
