H. Endogenous Ran, GFP-yTBP and proliferating cell nuclear antigen (PCNA; loading control) in nuclear fractions isolated from wild type yeast grown in regular and high salt conditions were analyzed by Western blot using antibodies for Ran, GFP and PCNA. I, J. Analysis of Ran and GFP-yTBP in nuclear fractions isolated from wild type yeast grown in regular and high salt conditions. The combined bar and scatter plot shows the band intensity ratios of Ran (I) and GFP-yTBP (J) over PCNA. Each dot represents an individual data point.
