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 H1-treated sample, which serves as an input control. Due to the absence of another antibody-based method for R-loop immunoprecipitation, validation of DRIP-seq results is difficult. However, results of other R-loop profiling methods, such as DRIVE-seq, may be used to measure consensus. On the other hand, DRIP-seq relies on existing short-read sequencing platforms for the sequencing of R-loops. In other words, all inherent limitations of these platform also apply to DRIP-seq. In particular, typical short-read sequencing platforms would produce uneven read coverage in GC-rich regions. Sequencing long R-loops might pose a challenge because R-loops are predominantly formed in cytosine-rich DNA regions.
