Analysis of the DNA Methylation Patterns at the BRCA1 CpG Island
... Data obtained indicated that Hpa II and Cfo I sites were methylated in human somatic tissues (including normal and tumoral tissues as well as fetal tissues, 65 samples analyzed) and cell lines. However, human sperm DNA was found unmethylated (Figure 1b). This assay allows a very rapid screening of t ...
