Experimental Details - HuPA_00028
Experiment type Mass spectrometry
Short description Histone modification analysis
Experimental description 293 HEK cells were collected and lysed and the soluble proteins cleared by ultracentrifugation. Histones were purifed from solution using rabbit polyclonal antibodies to histone H2A1.1 coupled to magnetic beads. The purified histones were isolated using 1-D SDS-PAGE and the histone bands excised. The histones were digested in an in-gel digestion and the peptides extracted from the gel slices. The isolated peptides were then run through a reverse-phase HPLC column into an ESI front-end to a QStar-XL.
