Description

technical field

[0001] The invention relates to gene detection technology, in particular to a CpG island methylation detection kit for tumor diagnosis and demethylation drug screening and its application. Background technique

[0002] A CpG island is a region of DNA with a length of about 0.5-2.6kb. CpG islands are unmethylated in normal tissues. But in human malignancies, altered DNA methylation is one of the most commonly recognized genetic abnormalities. Hypermethylation of many specific gene manipulation regions generally occurs at an early stage in malignant tumors.

[0003] The current method for measuring the methylation of 5โ€ฒ-CpG islands is Southern blot. The principle is that the methylation-sensitive restriction endonuclease cannot cut the sequence containing one or several methylated CpG sites. The method provides an estimate of the overall methylation of CpG islands, requiring a large number of DNA components, which can provide information on the methylation o...
