Bisulfite sequencing (BSP)
Bisulfite sequencing, or BSP, is an effective technical means to directly analyze and detect methylation patterns of genomic DNA. This method combined with bisulfite sequencing technology to further improve the sensitivity and accuracy of the detection. BSP is a very useful tool, which provides an effective means for us to understand the pattern of DNA methylation, and also brings new progress and enlightenment for the research in the field of biology.
Technical principle
By using sodium bisulfite to modify the genomic DNA, we can convert the unmethylated cytosine (C) into uracil (U), while the methylated cytosine remains unchanged. Next, we designed primers against the methylated sequences and performed polymerase chain reaction (PCR) amplification. After treatment by agarose gel electrophoresis, the expected product was purified and ligated to T-vector. By sequencing the positive clones, we can accurately understand the methylation of each CpG site. Finally, through statistical analysis, we were able to determine the degree of methylation within specific CpG island segments of a particular gene.
