Project description:Nucleolus-associated DNA was isolated from MEF cells before and after conditional knock-out of UBF and hybridized against genomic DNA in biological replicates. Two different types of immortalized MEF cells were used. MEFs were immortalized by genetic depletion of p53, iMEFs were immortalized by transfection of the SV40 Tt antigen.
Project description:MBD-affinity purification (MAP) was employed to investigate the DNA methylation status at promoters of mouse embryonic fibroblasts (MEFs), both wild type and Lsh knock-out cells.<br>MAP is conceptually identical to ChIP, using an affinity column rather than an antibody.
