Drip painting work of the mid-twentieth-century artists Janet Sobel and Jackson Pollock. Pollock found drip painting to his liking; later using the technique almost exclusively, he would make use of such unconventional tools as sticks, hardened brushes and even basting syringes to create large and energetic abstract works. Pollock used house or industrial paint to create his paintings—Pollock's wife Lee Krasner described his palette as "typically a can or two of … enamel, thinned to the point he wanted it, standing on the floor besides the rolled-out canvas" and that Pollock used Duco or Davoe and Reynolds brands of house paint.

DRIP-seq of different sizes. For massive parallel sequencing of these fragments, the immunoprecipitated material is sonicated, size selected and ligated to barcoded oligonucleotide adaptors for cluster enrichment and sequencing. To detect sites of R-loop formation, the hundreds of millions of sequencing reads from DRIP-seq are first aligned to a reference genome with a short-read sequence aligner, then peak calling methods designed for ChIP-seq can be used to evaluate DRIP signals. If different cocktails of restriction enzymes were used for different DRIP-seq experiments of the same sample, consensus DRIP-seq peaks are called. Typically, peaks are compared against those from a corresponding RNase
