Project description:The distribution of histone variants H2Abbd and macroH2A in 13 regions of the HG18 assembly have been studied using a variant of the ChIP-on-Chip technique. HeLa S3 cell lines expressing tagged histones H2A, H2Abbd or macroHA were obtained using retroviral transfer. DNA fractions associated with tagged histones were isolated using a two-step purification procedure that involved affinity chromatography on a column with anti-FLAG antibodies, followed by affinity chromatography on a Ni-agarose column. The obtained genomic DNA samples were analyzed by hybridization with custom NimbleGene genomic microarrays. Two samples. Test sample 1 is HeLa S3 cells expressing epitope-tagged histone H2Abbd and test sample 2 is HeLa S3 cells expressing epitope-tagged histone macroH2A . The control for both test sample 1 and test sample 2 is HeLa S3 expressing epitope-tagged histone H2A. Two copies of each probe per array were made.

Project description:To identify direct transcriptional targets of RFX6, we performed chromatin immunoprecipitation of HA epitope tagged RFX6 followed by massively parallel DNA sequencing (ChIP-seq). Using CRISPR/Cas9 gene editing, the HA epitope was inserted into the 3' end of the RFX6 gene in H9 hESC. Pluripotent cells were then differentiated into PDX1+RFX6+ pancreatic progenitors and endogenous RFX6-HA was immunoprecipitated with an anti-HA antibody. To eliminate background signal caused by non-specific antibody binding, a control experiment using wild-type H9 hESC was performed in parallel.
