| Hi, Does anyone have experience with FspI enzyme from NEB? This enzyme is common cutter for genomic DNA? the site of this enzyme in genome is quite less? I digested the DNA with this enzyme and it seems the resulting band are very large. Does anyone have some idea on this? Best wishes! Thomas |

| Hello again FRET! yes FspI (NEB: http://www.neb.com/nebecomm/products/productR0135.asp) is commonly used to cut genomic DNA. An example is this paper here: http://nar.oxfordjournals.org/cgi/co...ull/26/24/5734 Fragment sizes may vary from several kbs up... the above mentioned paper in some cases also used EcoRI... |

| Thanks! In this article, the FspI is used to cut the genomic DNA from E. coli. In human DNA, the CpGs are mostly under methylation. Thus. for human genomic and other mammalian genomic DNA, the Fsp I is not effective. I have tried and not detected any cut with southern blotting probes. May this would help the other people!
