Project description:Chromatin immunoprecipitation of genomic loci in Trypanosoma brucei where histone variant H3.V is deposited. This was achieved by deletion of one H3.V allele and N-terminal tagging of the second H3.V allele with a Ty1 tag. During the ChIP experiment, the DNA was digested with MNase to obtain mononucleosomes. Nucleosomes containing H3.V were pulled down by using a BB2 anti-Ty1 antibody. Cross links are reversed and mononucleosomal DNA is purified and prepared for Illumina sequencing.
Project description:Chromatin immunoprecipitation of genomic loci in Trypanosoma brucei where Scc1 is deposited. This was achieved by deletion of one Scc1 allele and N-terminal tagging of the second Scc1 allele with a Ty1-tag. During the ChIP experiment, the DNA was crosslinked and cells were permeabilized with digitonin. DNA was fragmented by sonication with a Covaris instrument. DNA bound to Ty1-Scc1 was pulled down by using a BB2 anti-Ty1 antibody. Cross links are reversed and the DNA was purified and prepared for Illumina sequencing.
Project description:Trypanosoma brucei gambiense is the causative agent of the fatal human disease African sleeping sickness. Using Digital Gene Expression we have compared the transcriptome of a group 1 T.b.gambiense (Eliane) and a T.b.brucei (STIB 247).
