FIG. 6.
Genome localization analysis of HA-Prp42 and Myc-Pol II. Cy3- and Cy5-labeled probes were synthesized from sheared genomic DNA or ChIP templates by linker-mediated PCR and hybridized with microarrays representing 6,229 yeast ORFs. Frequency histograms of ChIP scores [log10(median intensity fluorochrome 1/median intensity fluorochrome 2)/√2̄] for representative experiments (Cy3-genomic/Cy5-genomic probes, top panel; Cy3-U1 snRNP/Cy5-genomic probes, middle panel; Cy3-Pol II/Cy5-genomic probes, bottom panel) show a normal distribution, with outlying second peaks in the U1 snRNP and Pol II experiments.
